Have a 20gauge panel that i welded some brackets to. This warped the panel a bit and i tried to grind it smooth. But now, marks are showing thru the paint. What is the best way to fix this?

Thanks,

JB

If they are pretty good marks I would use body spot putty and block sand and then use a high solids filler primer and block sand again. You may have to prime and block sand twice. I got ahead of myself, Grind or sand your paint off down to metal first.

Something I use in the bodyshop is some stuff called evercoat metalglaze. Its a 2 part stuf like bondo it comes with hardener.It comes in a pint bottle.It flows out real good and sands easily with 180 grit.You can put it right over the paint , but scuff the paint with 180 or 220 first. That will give it something to stick to.Then smooth it out and primer.

I agree with big dreams, you are going to need some kind of filler in there to fill in your marks and smoth your part out again. I would advise against using spot putty, it is just a thick form of lacquer primer which will shrink after time.

The metal glaze will do what you want it to do and will not shrink. It is also easy to work with. :D
