What polish after wet sanding

Buy an electric polisher if you need one, Not an air polisher. Unless you have a huge compressor to feed it with. I have 2 Dewalts and a Mekita. Either one will work well but they arent cheap. Probably close to $300.

Its hard to go wrong with 3M polishing compounds. Either the Finness it or Perfect it line works really well but as Rob said the Norton stuff works well. I really like there Liquid Ice instant detailer.

I use wool pads for cutting and foam waffle pads for polishing. They have foam cutting pads also but I feel they cut way to quick. You can easily burn through the paint with them.
