Only thing for me is paint on threads. Cant do it myself. I would have to clean the threads and 40 them. Course its just a personal thing.
My thing about them is, if it's something that's going to be taken apart and put back together often, then I wouldn't paint over them. But those nuts and bolts holding on the backing plates aren't going anywhere soon. I get the "attention to detail" thing and it's great to have that gene, but I think, sometimes, it can get in the way of being practical.
For instance, this isn't a show car, yet I've done the filler thing on some welds. Someone would ask, "Why didn't you do that to all the weld joints?" And I'll reply, "Because no one's going to see them or even care and these welds looked like sh*t." This afternoon, I sanded the few runs and streaks with some 1,000 grit. My landlord, who's looking over my shoulder every time I start working, wanted to know why? "It looks perfect as is." My response, "But it's a section that will be seen on a "Bobbed" T Bucket, so I want it to look good."
So, I guess my attention to detail, as far as this car is concerned, is a practical, visual v/s non-visual approach. Of course, my first cruise-in, I'll come back to my car and there will be 4 people trying to crawl underneath and looking for flaws. My response will be my size 12 shoe.
