It adhered to painted metal (scored the paint), wood framing of the opening, plastic shroud and aluminum pressure plates. I am extremely satisfied with this product and from the day installed, it shows no wear even after a year. Excellent product... Another really good product is 3m 4200 Marine Adhesive... **Q: Will this bond to rubber?** A: Not sure about rubber, but everything else I happened to get it on and let dry it stuck like paint. My clothes, stainless railings, fiberglass cabin, teak of course, cork fishing rod handle, my leather wallet. . . **Q: can you use to adhere spoiler** A: probably work great ## Frequently Bought Together - Sikaflex-291, Black, General All-Purpose Fast Cure Marine Adhesive and sealant.
