Yeah, you aren't kidding on the body work part... painting is a piece of cake compared to body work. Even that little bit that I did on the firewall made me realize why quality body work and paint cost so much. It's just time consuming, manual labor mixed with an artistic touch....
Well since I have the week off from work, I started poking around on the car.... and basically went backwards in my progress
A couple years ago I had used POR-15 on all the interior floorboards. I had taken everything down to bare metal then used the 3 step process (marine clean, metal ready and then paint). Lately I've been taking the steering column and seats in and out a lot and I noticed that the POR-15 was getting pretty scratched up. What's worse is that in some spots if you put a screwdriver to the scratch you could peel the POR-15 away.
I used to be a big fan of POR-15, but not anymore. In one of the spots where I had scratched away the POR, I covered it up with Rust Bullet just to try it. The Rust Bullet seems to have a LOT better adhesion. I guess POR just doesn't stick that well to good clean sheetmetal and it truly is meant to go over rust.
If you look at the pics you'll see what I mean. In the valleys where I can't get the stripping disk in there, I would just poke out the POR with a screwdriver. In the one picture you can even see where there was surface rust under the POR.
So I hemmed and hawed for a while and thought about just going over the spots where the POR didn't stick.... but then I realized I'd start obsessing over it, so I decided to start over. So I broke out the drill and 3M rust stripping disk and after a couple of hours I had most of the drivers side back to bare metal. I guess I'll keep going tomorrow and do the passenger side as well. Now I need to figure out if I want to go back over everything with Rust Bullet or just PPG epoxy primer.
The Rust Bullet seems pretty tough and seems to stick to clean metal very well.
Thoughts?
The Rust Bullet would be a lot easier to apply since I would brush it on and wouldn't have to mask anything or worry about overspray. Of course the epoxy primer is meant to go right over the bare metal and provide a corrosion barrier and I know it will adhere well although it's a pain to apply and I'll have to mask everything. Hmmmmmm
