I use meguires m105 compound for scratch removal and then step it down to the m205 finishing polish. I use a dual action polisher with different foam pads for cutting and polishing. Its a art to get things right. On this car I had to use my rotary buffer with a wool cutting pad too

Here's a chart from Auto Geek:

Alex - I've had good luck with Meguiar's Scratch-X product - It's an easy wipe on buff off for problem areas.

I'll be trying the Four Star Scratch Remover & Ultimate Paint Protection this year as a change from Zaino (But you won't find these locally)

Back On Topic - That Car Looks Amazing!!:bek068: I hate Black for the simple reason it's Extremely Hard to keep clean - but when they are clean there's nothing better looking!!

Thanks man. And you are def right about black. I told the owner of the vette if he needs to wash it go to a touchless wash. LOL. He said he will just bring it back to me once a month to stay up on it.
