I’ve got my engine out, doing some routine maintenance. My car is pretty crusty, kind of looks like it was done back in the day. Now’s the time to paint the firewall. I just don’t want it to make everything else look worse. I’m concerned that if I paint it, I’ll have to start cleaning and painting everything on the car. I kind of like the crusty look. Maybe I should paint the firewall, then clean and Gibbs everything else. The paint on the firewall wasn’t prepped correctly in the ‘60s or ‘70s and is flaking off. Should I paint it or just clean it? If painting what color?
