Anyone know if this can be done? I was thinking about lining my floor in Dynamat to shield the heat and noise from the 5.4l. Problem is I want to coat it in bedliner too. Anyone think I can add the dynamat then spray the dynamat? Will it hold? Last?

 

why not just try the lizard skin. i think thats the name of it. its a really think under coating and its designed to sound deaden and keep heat out.

 

hmm not bad.

it doesnt really say if its a finished surface though.

 

I've seen it used on TRUCKS when they were doing the 79 Crew Cab. They did it on a primer floor, no reason why you couldn't just scuff the floor and lay it on

 

is it much different than linex? i can get it linexed for the price of materials. Neighbor runs a shop. so maybe I should just do that and forget the dynamat.

 

I don't think it's much different from LineX

 

If you can get line-x for cost of materials, I'd probably go that route. Dynamat won't help too much with making the engine noise less, that's more of the job of closed cell foam.

 

as far as painting dynamat goes, i don't think it'd stick.

 

Line x the inside and spray the lizard skin stuff under the cab, that will sound deaden it.

 

Thanks guys. I guess I will just go with the linex then. I just want something easy to clean and looks nice. Right now its just gloss black. lol

 

Line-x is the way to go. Dyna mat gets expensive real fast and doesn't work too well IMO.

 

I agree just spray the entire thing and be done with it.

 

IMO and no experience with DynaMat but the top layer is not a good base for paint of any kind; shiny smooth aluminum.

Downey’s idea of spraying on a deadener is the best thing, there are others though like Fat Mat; $80/gal shipped.
You can spray it with a 30/1 mix so it gets in all the little spaces, or brush it on. it is water proof if applied with good prep.
FatMat dries black, might be good enough if that is the color you want.
