    I'm cutting a piece of diamond plate to cover the old firewall up on the Willy's. Should I use rivets, or monkey snot? I plan to seal the whole outer edge with silicon so water can't behind it. Any feedback will be appreciated

    The stuff I have is kinda thin so it is easy to cut and work with. Just use a saber saw or jig saw with the right blade. later on I'm going to add a strip down the bottom edge of the body.

    I'd definitely go with rivets or screws - we had an engine drop the big panel (glued) above the tailboard while running down the road - $300 and alot of cutting, fitting and swearing later, it's screwed on now.

    That'd look nice! I've seen quite a few fire department Suburbans with diamond plate side panels, and even a couple of Blazers.

    Just never use the stuff to make an engine housing - especially over a turbo. I've got that pattern permanently etched into my leg from getting it too close when the engine was hot - it only took fire apparatus builders about 30 years to figure it out.

    as a mechanic on aircraft i would say both.
    reason.... you have dissimalar metal. aluminum and steel. as they rub together with rivets it will scratch the paint off, gorilla snot will stop this. but it wont hold all the way with flexing over time. rivets will last a lot longer.

    Rather than "snotting" the whole firewall, you could get away with a couple coats of primer on the back of the diamond plate, and a coat of primer on the firewall. As long as there's no bare steel touching bare aluminum, you'll be OK from a corrosion point-of-view. Put a little snot on the rivet shanks before you put them in the holes to seal them, then snot the seams like you said you would.

    Around here we call it monkey snot, it is an automitive adhesive used for trim panels and such. it is real messy and tacky.

    In the Marine helicopter community I work in, "gorilla snot" is polychloroprene adhesive. BUT, it kinda applies to any adhesive or sealant.
