Hey, copgtp, you're one to talk about jumping into things, you haven't the slightest clue what he used. I'm his older brothe, I do know, we used a soft cloth with white rouge compound on the inner walls. I have since ridden in the car and it made a significant difference in his car. And concerning him not knowing anything, our dad has over 25 years experience building motors, I think we know not to change displacement in a P&P. Ease up, he's new to the forum and gtps, and he is 16 years old at that!
