Fiberglass is a very durable material that will bond to almost any surface, including plastic, metal, wood and Styrofoam. For laying up fiberglass on hard materials such as metal it’s important to thoroughly scuff the surface to get a strong bond.Click to see full answer. Likewise, people ask, how do you bond fiberglass to steel? How to Bond Fiberglass to Metal Rough up the metal surface with a piece of coarse grit sandpaper. If bonding fiberglass gelcoat, rough that up too. Mix up a batch of the epoxy large enough to bond the fiberglass to the metal. Apply the epoxy to the metal surface and the fiberglass surface. Also Know, can you fiberglass over body filler? Yes,you can fiberglass over bondo,rough the bondo up with 80 grit for a better bond,use a grooved roller to remove the air bubbles. DO NOT use Bondo on a boat, it will swell up when wet. Also Know, does fiberglass stick to stainless steel? Fiberglass will stick to metal but after time it will release. But you can use adhesive on dry fiberglass, but it sounds like you are talking about putting wet fiberglass on top of metal. If this is so, then it won’t last long unless you give it some to grab on to.Can you fiberglass over aluminum boat?You CAN successfully fiberglass over aluminum.. it’s done on Aircraft every day but you’ll need some epoxy polymer resin. Boat resin wont stick well because it cures too fast and is not a structural epoxy adhesive. Get you some “Neat Stuff” spray insulation foam.
