Need to patch some pinholes in my floor board. It's still structurally sound but I'd like to keep the water and fumes out.
No patch panels available and not sure I'd go that route anyway as it's just a driver not a show car.
I've ground all the surface rust off and will treat with rust bullet converter and clean with mineral spirits before application.

Anyone have any recommendations on a good metal patching epoxy?

I ordered some stuff from Amazon to try but appreciate real world experience.

Thanks

 

If small holes simply fill with jb weld, if I tad bigger jb weld some sheet metal onto the hole. Cheap and effective, just be sure the areas to glue are super clean. You can always wire wheel the area, jb weld then spray a 2k etching or epoxy primer on top. Or you can simply paint with a roller and rustoleum oil based paint. Will last many many years.

 

If you're going to use JBWeld then get the quick dry version. The regular stuff will run and drip down through the holes. Or...clean and tape off the underside of the holes if using regular JBWeld.

I'm assuming the original J B Weld. There's a bunch of different ones.
I'm gonna top coat everything with rust bullet automotive and considering adding Kilmat insulation over that.

 

Filled the bigger holes with JB Weld stick epoxy, let it cure then scuffed and covered with JB Weld original. Tough as nails.
The lighter stuff is something I bought on Amazon. It works ok. Feels softer but I only used it on some very small pinholes just to see how it works.

Now to coat with Rust Bullet.

 

Make sure you post an after pic once you coat it with Rust Bullet.

 

3 coats of Rust Bullet.
Brushed. Spray would ha e been a nicer finish but since it's a floor I wasn't going through the trouble.
