It would probably stick to water. D Review: Easy way to fix the rain sensor . - Works as advertised and is really easy to do. The hardest Part is to get the cover off from the Mirror assembly, but even that was easy. There is not much needed and with a 3 year Shelf life, you have enough left in the tubes to get it done again if needed. Great Product. I would recommend this over fixed gel pads that never will connect to the surfaces as this liquid is doing. Actually there was a gel pad installed before and it failed. That’s why I had to do this in the first place. Definitely recommend this product. ## Features - Adhesive and sealant used by many boat builders, its fast cure time makes it ideal for applications where speed is important. - SUPPORTS: Excellent adhesion to gelcoat, fiberglass, metal and wood. - DURABILITY: Resistant to fresh water, sea water, limewater, sewage effluent, diluted acids and caustic solutions, temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils. - PERFORMANCE: Used above and below water line.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good *by L***O on 5 August 2026* This is a very good product.
