No, not what you're thinking. The paint on my ERA Cobra is about 7 years old and was showing signs of primer shrinkage all over the car. The paint, guardsman blue with wimbledon white stipes, is clearcoated had a great gloss, but upon close examination you could see a crosshatch pattern. This has never bothered me too much, but I figured that since I am about to list the car for sale that I better make it right.
My concern was that the car had been color sanded when the paint was new, so I was at risk of going right through the clearcoat. This is an expensive mistake that I didn't want to make, so I had to be content with not getting the surface totally level. I was really surprised that using only 2500 grit paper that the marks are 95% gone. Fortunately, the sanding dust never turned blue...
I tried to get some detailed shots of this crosshatching for those of you who've never seen it, but I just don't seem to have the ability to capture it, so no 'before' pictures.
After wetsanding with 2500 paper I made two passes with 3M 39001 medium cut compound using a grey 3M waffle finishing pad on my rotary at 1750 (the only speed it has!) I've never used the 3M compound before, but I really like it and plan on using it again tomorrow when I buff the s/s lacquer on my 1930 Model A coupe. I followed this with a couple passes using 106FF with a white pad on the UDM. For the LSP, I initially went with Duragloss 601 bonding agent and 105TPP. The gloss was outstanding, but after discussing it with my son, I decided to top it with S100 to give it a bit more depth and the vintage look that I was after.
