Alright, I was able to run out to get paint and degreaser sooner than I thought, so I spent some time on the car today. I painted the first wheel well with Rustoleum undercoating, and 8 hours later it's still not dry. I'll check it again tomorrow, and if it didn't adhere I'm going back to my original plan of 3M undercoating. Not sure what the issue is. I forgot to take pics of that, I'll post them next time. I also sanded down the other side rear wheel well but I'm holding off on paint until I see what's going on with the undercoating.
I also started sanding and painting some of the parts that I took out of the car, in the hopes that I can start putting it back together in a couple of weeks:
I also painted the exhaust with high-temp paint (see previous post for "before" shots):
And lastly, I sanded and re-stained the wood steering wheel, and painted the center a satin black instead of the original chrome. Looks good so far, some finishing work needs to be done though.
