Hi all, picked up a lund visor not long ago. Its a black one. Searched for a long time to find a Lund Visor, finally found one! Any of you guys using one on your truck? What is the best way to attach it? Im torn between rivets and self tappers.
Wow, haven't seen one of those in years. Had one on a 1989 Ford F-350 I bought new in 89.
Personally, I'd go with some stainless steel self tapper screws. No worry about rust. I would also advise you to get a roll of butyl tape and use a layer of it where ever the visor contacts the roof, especially around the screw holes.
I use plenty of butyl tape on my motor home, and have never had it break down or leak. It will also allow you to remove the visor without damaging the paint.
It will prevent water intrusion into the roof. Don't use any type of silicone sealer as it will deteriorate over time.
The use of screws over rivits will allow you to remove it if necessary without having to grind/drill out the rivits.

They are certainly hard to find around here that’s for sure! I’ve wondered about the butyl tape you mentioned. I plan on putting on a few cab lights too eventually and noticed they utilize a foam gasket. How good does butyl tape hold up over a rubberized sealant compound ? Reason why I thought about the rivets is because they wouldn’t loosen up. A friend of mine has rivet nurserts too
I'm in your boat, have the visor, getting info on mounting best way to fit it up to the truck.
I plan on using a good quality stainless steel sheet metal screw, the exact size... I'm not sure yet; I have the Caps to go over the mounting screws so far, I need to determine the size of screw used in the Cap Locking Rings.
I had someone post in my thread about using Pen Nuts, the starting holes will need to be larger but using a sealant like Grumpaw posted is a good choice. Two problems I can see about Pen Nut are, If you remove the Visor, and don't want to put it back on the holes will require more work to fix and it will require a special tool to install the Nuts; other then that it could be a viable choice.
I was thinking of Windshield Sealant, not sure what its made of, all I know is it stay softer than other sealants and is DOES SEAL !
Will do. Working on doing up the front end a bit then fitting on my new tires. I think the cab lights and the visor will set it off.
cap screws seem like a decent idea with the caps if you can find them locally. As long as water can’t get in there shouldn’t be much or any rust. A rubberized compound would be a good idea I’m thinking cause it will flex and be less likely to crack overtime. I seen at the local dollar store 3 m foam tape that looked similar to the butyl tape too for the added cushion
First the "Cap Screws"... I will be using S/S Sheetmetal Screws, with separate Plastic Caps and Locking Rings. (The Locking Rings goes under the Screw and then the Cap snaps on)
Foam Tape IS NOT the same as Butyl Tape or even Windshield Sealer, as I plan on using. Get the actual Butyl Tape, it is thick rubber based tape that has a little give to it and when a Screw is screwed through it Butyl Rubber will secure around the screw and in the threads to seal up the hole and threads and takes out some of the vibration from the visor.
IF 3M makes Butyl Tape in strips, then do that but I for one do not think Foam Tape will work, it will wear out faster than you think and then you have two problems, one no sealing material and you end up with Fiberglass against paint, I don't think I need to tell you what will happen.
Look on line and see what companies, that sell Windshield Visors, suggest for a sealant, then decide what to use; you don't want to have a do-over !
Do It Right The First Time !

p.s.
I like the Moon Visor, my '88 STX High Boy, had the Moon Visor ,I wired it into the parking light circuit, securing the wiring was a problem until I sanded the fiberglass, used epoxy and it held things in place.
My latest Visor, is a standard Visor, that I added the newer LED Lighting, small oblong LEDLights, I positioned them similar to the Moon Visor.
AND don't forget the extra hole for etc wiring by the Driver's side, don't want to attempt a hook up and then find I need to remove the Visor... PITA !

Butyl tape is the product that the rv industry uses to seal items to open cutouts. Windows, door frames, compartment frames, vents, access doors, ect. All use butyl tape as a sealer.
IIts inexpensive, and it works.

Where did you buy this Butyl Tape... or was that a give-me from work ?
I am doing the same project and will checkout Lowe's and Home Depot, not sure where to go for it !

Thx Grumpaw for the advice !
You won't find it in Lowes/Home Depot. Best bet is if you have an RV dealer/RV Parts dealer in your area.. It's a must have inventory product for any rv dealership. Never been in an rv store that didn't have it in stock. Also, check any marine dealers in your area, if any.
I.ve never checked them but may have it.
If none available, then Amazon.
I keep a roll in our motor home's tool/parts kit. Used it mucho times in the past. Even if you have to buy a roll, the stuff dosen't go bad. It will keep forever.
Just get the standard gray tape. 1 inch wide x 1/8 inch thick, 30 foot roll will run you 12-14 bucks.
When you apply it, just make a single layer on the part you want to attach, and cover the area all the way to the edge. When you attach the part, and start to tighten the screws, you'll notice some of the tape product will squeez out. Not a problem...supposed to do that.
Just take a plastic scraper and scrape it off.

I found some 1.5", 3M, Butyl Tape at an On-Line Store, $54.+ for six 30 foot rolls, obviously I don't need six rolls, so I e-Mailed their Sales Team and we will see.
Yeah, you have to order it. I remember looking locally too and I could not find it anywhere. The wrong stuff is .. the wrong stuff. You have to order it. Frustrating when you have some time available to do some work, but sometimes you have to wait to do it right.
This is a pic from eBay, shows the 1.5" width, grey compound, and it is said to be flexible !
$30/roll, but should work !
It is 1.5" wide x 1/8" thick, 60', should be enough to mount the Visor and then some !
I like the idea of the 1.5" wide tape, it would cover the width of the mounting pad and allows for roughness in the underside of the visor, it would be able to be run the full length of the mounting point to the upper edge.
Again, not sure but I have been searching on this stage for a couple of hours and this is the closest I have come to what I think the product should be and what I think I want !
Waiting to order but I think this is it.
Thx to anyone for an assist !

Yup Scrambler, that is butyl tape. 60 feet is a bit of overkill. And the 1 inch wide stuff is just as good...you just have to run several strips along the area your attaching.
But whetever....that photo is it.

So effectively the butyl tape works as a gasket i assume? Similar to a plain gasket / gasket material. So if i go ahead and use self tappers, and use this for a " spacer " for the visor to rest on i should be good? Should i cut a gasket piece to fit under the self tapper or just sealant silicone over top of the tapping screw after installed? I know as long as water doesn't have to opportunity to get in then there should be no rust or very minimal. I looked up some Butyl tape, came up for a lot of marine applications! I am always interested in marine silicones and paints because to me that is the stuff you want to be using cause waterproof is of most importance. I think when i give my frame another coat of paint again this year i'll be using two part marine paints. That stuff hardens like a rock!
NL: My opinion (and it's only an opinion) is that you are better off using the butyl instead of silicone. The silicone will bunch up and allow water in later. The butyl is going to stay where it lays. I'd use butyl under all the screws, this way you don't have to worry about it later. If it seals good the first week, it should last the next 5 years. If not, then you know you have to go back in. But with the silicone, it can last 6 months, 1 year, 2 years, who knows?
Ditto... my install has changed a little.
I WILL be using the Butyl Tape I posted above. O will clean up the under side of the Visor a little and lay a strip of this stuff over each area that will come in contact with the Cab.
My intention is to run it from the back edge forward to cover the front mounting hole and then some, based on where the Cab contact the Visor.
As Grumpaw has stated, you can cut off the left overs so I will use more than I think I need.
Then I will use little pieces of the Tape rolled in a string, wrapped around the self tapping Screws, this should seal the top as well.
Not sure if this makes sense or not but I DO OVERKILL on everything and I would rather be safe than sorry !
Thanks to all for the info about Butyl Tape, I wasn't sure where to go on the sealer and this stuff will make a great gasket also.
One thing about using the woodier Tape, do not tighten the Visor down completely, tighten it to a snug tightness, let it set for a while and then go back and tighten it but remember the Tape is thinned soft and if you tighten it too much you can push it all out of the contact points to the cab.
I have never done a Visor install before so I am winging it and I may go back and tighten it all the way down but I will do it in steps to see how it is holding on.
If someone has an opinion on tightening the Visor, please post, I do not know for sure the best way to handle this.
Scrambler, don't overthink this. Just make a "pad" for each of the areas that contact the roof. Single layer of tape. I also believe in "overkill", but in the case of butyl tape, if one layer is good, a second layer IS NOT a good idea unless your trying to fill a slight gap or depression. When you tighten/snug down the screws the tape will compress a bit. Don't over tighten the screws as the fiberglass around the screw hole may crack.
And don't worry about the visor comming loose...that tape, while not a "glue" based tape, will act as an adhesive. I have 3 vent fans with covers on the roof of our motorhome that have been taped and screwed, for 7 years now. Still as secure and waterproof as the day I installed them in 2012..
All those motorhomes and rv trailers you see on the road...they all use the tape for multiple sealing areas. Bought my first rv camper in 1970, and butyl tape was around even than. No one has come up with a "better" way.

I priced butyl it’s pretty cheap here locally, seen it at the Home Depot. For me I wouldn’t wrap butyl around the screws themselves, I’d just put the screw right through the butyl that way it’s more of a simple gasket application. But seems like a good idea. Once exams conclude I’ll be working on this project! Truck is getting painted this year too! Will do either normal black again or full on raptor lining the truck ha!

Thanks and yes I over think everything, one of my "ADD" problems.
I have to think on it and procrastinate for a week or two or more just to get myself in the groove to get it done, then when I start I see something else that needs to be done... pure PITA !
I understand what you are saying about on layers, I will do a single layer under the Visor but will add a little more under the screws for "Just In Case" !
I cleaned up the visor, used a counter sink on the screw holes not deep just a little, more to clean them up then to add additional sealant, but in watching a video about installing the visor, the screw sealant thing came up and I liked it !
Also, the visor I got has some stress cracks in the Jell Coat, I now will be smoothing out the fiberglass under each mounting point and adding a thin sheet of Fiberglass cloth and resin for additional support, but the Jell Coat... I am not sure if the new paint will cover it or how to handle it !
My thought will be to have the painter fix it up !
Thanks for the help, sorry to the OP on using his thread to get this sealant thing done but hope he got something other than Foam Tape to seal up his visor.
