I had a similar problem when painting my car, the paint shop mixed part of the paint wrong and I painted it. Then I looked at the paint and I could not sleep that night. I have also had every single nut, bolt, washer, etc. replated on my car, if it came from the factory it has been replated. I ended up repainting my car because it would have driven me crazy. So if you have lost sleep then repaint because it will just drive you crazy, at this point in your build what is another $2 or $3k. Because i know how much I have in my build. On a side note if you need any new rubber parts check out my thread http://www.classiczcars.com/forums/garage-hobbyist/49264-240z-fuel-brake-line-insulator-sets-steering-rack-expansion-reservoir.html
