Painting inside cab and firewall
I am getting ready to paint the firewall and inside the cab on my 1951 3100. The truck was originally maroon but some dickhead apparently chemically stripped the truck so there are only little shreds of color here and there remaining. I picked a metallic burgundy PPG mixed as a single stage for the inside and firewall -- the rest of the truck will be cleaned of the worst rust and grunge and treated to a coat of Penetrol.
Questions: where do you break the paint, specifically around the hood mating line and door jambs (see pics)? I'm thinking about the paint being exposed through the gaps and would like to minimize that. I'll back tape the edges to keep it a soft edge but I'm thinking I may want to set the paint edge back about 1/4" from the actual edge. Make sense? Any better way to do this? I searched for pics but it seems like everyone takes pics of the engine bay or interior only. Also, I know I already primed to the edge but I can easily sand some of that off to pull the paint back further. All thoughts and suggestions appreciated! Pics would be great too. Thanks!

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.

Re: Painting inside cab and firewall
Foot - I may not have explained this right. For the firewall and inside the cab I sanded the surfaces and I am using standard epoxy primer followed by the PPG paint.
For all the rest of the exterior sheetmetal -- it's rusty and a full paint job isn't in the budget now. I am clearing much of the rust and dirt and grunge off using CLR or a similar product, cleaning and drying the surfaces, and then wiping on Penetrol to slow down further rust. No primer or paint at this time on these surfaces. Make sense?

Re: Painting inside cab and firewall
Scott, thanks for the clarification but I wouldn't get anywhere near it with that stuff. Period. You're better off to let it rust than use Penetrol, seriously! Your truck, your project. Epoxy primer is cheap, easy to use and does as advertised. Besides, there isn't an automotive paint manufacturer that would approve of your methodology.
I hope you reconsider.

If Penetrol is still a poor choice, whats the alternative to slow rust but otherwise leave the patina alone? Thanks again!

Here's a good example of a patina truck with Penetrol (thanks 74project):

Re: Painting inside cab and firewall
As always, I really appreciate all the inputs and wisdom from the members here as there is a wealth of info and experience that helps me tremendously - thanks all!
I wanted to share the results of my painting efforts and you can see where I chose to set the tape lines. I think this will work great for now. It will be more work if I decide to paint the exterior later but I’ll deal with that when I get there.

Re: Painting inside cab and firewall
Yes. I replaced the floors, seam sealed, primed and painted them black, then applied both kinds of LizardSkin, then Dynamat. Now I have a roll of automotive carpet to put down in a spare moment.
