Re: Painting inside cab and firewall

You break the paint where you can't see it with the doors or hood closed.

In over 20 years of supplying paint and bodyshop supplies, I have never heard of anyone using Penetrol... never even heard of it before your post... I looked it up and can honestly say I wouldn't use it. You are not going to use oil based paint are you which is what Penetro is designed for... or are you? What you should use is an epoxy primer, regardless of brand.

Epoxy primers lock in surface rust and will not allow rust to creep under it if there's ever any damage to it. Epoxy primer is along time, solid, proven primer for bare steel for which there are no substitutes.
