Paint and primer help

just knock it off with a da and 80 grit and cover with your favorite epoxy primer.

it is not clear if you are talking about a quarter panel or the trunk floor or?

I would not use a direct paint over rust product like POR 15 or Rustbullet on the exterior of a panel. In order to get the thickness required for it to do its job(encapsulate rust) it would look terrible.

Thanks Chris.

I was wondering about a "Rust converter" and not a encapsulater.

I'm on the firewall/cowl and the frame rails, rad support. No inner fenders since the late B body cars have them bolted in. I have small time windows in which to work in. This makes the process slow. I have a lot of exposed metal at the moment and a few good days until the next forecasted rain on Sunday.

I would like to produce a nice firewall. Since everything else is some why hidden and less of an attention getter, a show quality finish is not expected. I would like a nice driver since I'll be driving this everywhere. But certain area can and may lack. This, I'm OK with.
