I have painted many cars. I have color sanded cars. I have buffed cars. I have detailed cars since a teen. I have never used a clay bar. My truck needs a good coat of wax. I really should try a clay bar and compare 1/2 of the hood with and without it. It's the original single stage paint.
The only thing I can imagine is the clay fills in some of the scratches to make the paint appear flat? I understand it's billed to remove contaminates...but, I would think a thorough wash would do that...
Looks good. I just always wondered if clay bar really makes a difference as one of the steps in the process.
