Default Advice on spray adhesives

Hello all, I need advice on the best type of adhesive to attach foam padding inside my fenderwells for rock and stone protection on an aluminum car. I've tried the foam with the adhesive backing and it doesn't last very long before it comes loose, so I'm looking for a more permanent method. I'm looking at spray adhesives like 3M super77 or 3M General Trim adhesive any suggestions? I've heard that some products will melt some types of foam. Thanks for the help!

I used 3M Super77 and it hasn't let go yet. The general trim adhesive is meant more for headliners and door panels.

The Super77 works very well. Spray both the inner fender and the foam, then let them get tacky (about 1 minute) before putting them together.

Why not try some spray truck bedliner. It would last forever.

Contact cement, Home depot.

Apply to both surfaces, let dry. Carefully (and I do mean carefully) apply the foam and forget about ever getting it back off.

You can also apply an additional coat to the dry coats and install it while still wet. (this will let you make some adjustments)

This stuff is very fumey, open the window first.

Yo Ronbo. That thread was from over a year ago.

Default Undercoating or lizard skin

67500 To protect your aluminium body either multi layers of undercoating or that newer stuff out Lizard skin. I added 4 coats to the rear wheel wells for my car. Tape everything off and have a nice day to spray it on. NO BREEZE DAY and a temp in the 60-70's. Repeat and apply. Rhino bedliner would be the other idea, the colors include silver and it is thick after setup. About 1/2" The other choise is carrying a smooth hammer and dolly for the body work. ONLY kidding. 3M will glue just about anything to any thing, but you have to watch the heat area. It also doesnot like water and breaks down over time. Rick L.

Smile Fenderwell undercoat

I'm going to undercoat my fenderwells, soon. I put it on my "things to do, this winter list". I still have a week or two before spring starts.
I stopped by the parts store to see what was available. They had 5 or 6 different brands or types.

Question, what should I use to undercoat my fiberglass Cobra fenderwells? Brand? Type? Pro/Cons

Thanks
Dwight

Default patch test

Dwight Get the middle of the road price ones, Like Peramtex. Do a small patch test and let cure, Do this a couple times. Then check for pealing. If OK shoot away, after you tape and cover where thing that you don't want sprayed. Rick L.
