I have a 2000 GT with 155,000 miles. It has black paint with a lot of imperfections. The car was crashed then rebuilt and repainted by previous owner. He did a HORRIBLE job! Theres overspray, craters, bugs on the front of bumper that got sprayed over!!! And on top of that, the paint is fading, there are scratches, etc. I need to know the best wax, clay bar, and polish out there. I use turtle wax original and it works great! Also, if I use a polish, do I need a buffer? I have one, I just hate using it. And what kind of spray do you use with a clay bar? Thanks!
