Fiberglass is a non-corrosive material that can be used as reinforcement or as a repair patch on almost all surfaces including metal, plastic, and wood. Typically, fiberglass is used for rust repair by replacing the rusted metal and sealing the surface.

Does JB Weld work on rusty metal in this sense? Yes, as long as it is thick enough. Too thin a coating will eventually cause moisture and oxygen to reach the steel, just like other coatings. No polymer will stop corrosion over time.
You can use a hard piece of cardboard, a kit applicator, or a putty knife. Make sure that you apply epoxy until the entire hole is filled or repaired. Epoxy will form over the metal surface and the edges of the hole will overlap a bit.
Body filler is not good for rust repairs. You cannot slather some Bondo over rust and expect it to stop the rust or stick to it for that matter. … If there are holes in the metal, you are much better off cutting it all out, patching it with new metal, and then working the body filler from there.
Another option for gluing metal is Loctite Epoxy Weld Bonding Compound. A convenient alternative to welding, it’s the strongest solution for bonding most metals, including iron, steel, aluminum, brass, copper, and pewter.
Epoxy is a super strength adhesive that usually comes in a twin syringe containing resin and a hardener, hence the name ‘two-part epoxy’. When these components are mixed they create strong, lasting bonds. Epoxies are especially useful for heavy duty repair when fixing materials such as metal or wood.
Fixing a rust hole in your car requires first removing the rust and any affected metal, and then filling the hole with a fibreglass body filler. From there, it’s just a matter of giving the repaired area a finish that you’re happy with.
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.
WD-40 Specialist® Rust Remover Soak quickly dissolves rust and restores tools, equipment, and surfaces to bare metal without chipping, scraping or scrubbing.
Simply soak the rusty metal object in white vinegar for a couple of hours and then just wipe to remove the rust. If the object is too large, simply pour white vinegar evenly over the surface of the object and give it some time to settle.
Body filler (aka bondo putty) and JB Weld are two completely different things, and are meant for different uses. You shouldn’t be using JB Weld as body filler, and vice versa.
Beware when painting over JB Weld. It obsorbes mousture like crazy, and you must dry it well before painting it. Sometimes, if you let it dry on its own, there will be a wet mark around it for days.
Bondo Body Filler cures fast, shapes in minutes and is formulated to be a non-shrinking and permanently durable material. In addition to its uses on vehicle exteriors and other metal surfaces it is also a suitable repair option for wood, fiberglass and concrete.
J-B Weld Original was the first product created in the J-B weld product range and is arguably the most versatile. J-B Weld two-part epoxy cold weld system. J-B KwikWeld provides strong, lasting repairs to metal and other surface types.
The basic answer to the question “can you use epoxy with steel and aluminium?” is yes, you can – but the trick is to make sure you’ve prepared the surface thoroughly first, to get it back to ‘bright metal’.
if you try to just weld up the rust holes, the rust will be back in no time and be just as crappy a repair as the bondo was. remember after you weld, you’re gonna grind and thin the sheetmetal even more.
Your car is important to you and you want to take good care of it, so fortunately, there’s something you can use to remove rust from metal without damaging paint – WD-40. … To remove surface rust, simply spray it on the rusted surface, leave it for around ten minutes and let it get to work on the surface rust.
