one thing I didn't explain is that my theory on the first round of prime, in which I think 3 coats should be applied, I sand and sand and sand til metal pokes up. The old painter once told me I "overprepped". No such thing on the first round. You want to sand it off to make it easier on the next round. So basically on the door it was just back and forth til something showed up or poked up. This makes it important to do tight coats of filler cause you are most likely gonna reveal it with all that blocking, and you don't want to reveal pinholes while doing it.
So in this video I noticed the doors and fenders were about equal to the quality of the body and roof. How is that when the body got primed once and the doors and fender primed twice??? They were primed the first time by the old painter that would put two thin coats on there on the first round as opposed to the 3 coats on the body. So how could 3 coats of primer look better than 4 coats of primer??? The 3 coats "up front" made the total difference. Now I know this all sounds like an excuse but if you want to key into details you gotta pay attention. I'm pretty sure I was the only guy in the shop to pick all this up. The good thing is, everyone is happy about the quality except me, so that's a good thing.
