Relays that won't corrode

I installed some after market fog lights in my truck back in July. Since then the relays I have been using (standard ford relays, taken from the junkyard) have corroded on the inside twice and stopped working. The relay is located under the hood, by the battery.

Are there special relays that are sealed that can withstand this environment that wont corrode?

Make sure you buy waterproof relays or Marine Relays.

Could be pricy.

Is there water/dirt being sprayed on them ?
Are they mounted with the prongs up or down ?
Funny I have had relays last for years.
I bought some Waterproof Relays for my first Ranger, a long time ago and never installed them but was going to on this one, I got them from Desert Rat; not ever sure they are still around.

Well they are under the hood so there is some dirt and water that is getting splashed onto them. The relay is kindof mounted sideways. I will take a look for marine relays.

Relay-Flux Tight

I think this is the one he is talking about but there is not pic.
There are other types out there so look around.
Mount the relays with the wires going down.

Here’s one I just found: http://www.route66supply.com/store/page85.html
A little more money but they are sealed.

My other thought is just get new realys and a tube of silicone and just goto town on them. I dont care if the blades corrode its the insides that get messed up.

Could work, silicone the edge of the relay where the insides meet the case.
Mount the relays with the pins down.

Should help a lot.

Luck,
