Yes. Many times. Sealing it is bad news, but you a free to choose whatever method you prefer.

 

Without a seal, there is enough gap to wash between with water. It's also enough to dry out of moisture gets in. With a seal, stuff will still get in except the seal does a great job of holding it in. Constant moisture is your enemy and a seal will get you that.

Same thing with axle seals. Crap still gets in, but can't get out.

 

Here you go, this is what was waiting under my corner armor a year after it went on. It's not as bad as it looks. The rust was actually from the armor itself not being prepped properly and was transferring rust into the clear coat of my paint. The nutserts did not provide any standoff and instead my body was slightly warped and puckered which just made the two rub together even worse. I could see running a gasket along the top edge of the corner armor to keep water from going down in and then not sealing the bottom so that any moisture can drain out. Not sure how well that would work or if it would even help at all.

 

A friend of mine runs a 1/8 bead of silicone around the holes and just inside the outer edge and lets it dry for a day, keeps the water out and the armor away from the sheet metal, this year I'm going to give that a try.

 

I can see the pro's and con's to both choices. Tough to say which method is best but I prefer to use the rubber seal on the rocker armor and fender flares due to all the contact with rocks. I don't think there is a seal available for the corner armor although if there were, I wouldn't use it as it would probably cause the corner to not fit properly or snug to the tub.

 

Are you considering the PS Sliders? If you are you need to PM me first.

 

No. Just PS body armor. Going with rockslide engineering for sliders.

 

I'm looking at the PS sliders

 

Paint works just fine. if you get the steel then its not an issues if you get the alum then you dont want the 2 metals touching directly so just paint them or if they are alredy painted your gtg.

 

I've got Evo's aluminum rockers (with VKS sliders) which I'm planning to have painted body color. I have heard about the corrosion possibilities if using a rubber liner like the one PS offers. Interesting since Evo's instructions actually call out the applying of a gasket sealant to their rockers prior to installing....

I'll probably skip the sealant...
