If you want it really good...
1. Clean your Jeep
2. 3M makes a buffing compound in a purple bottle, use it with a white waffel pad on an orbital
3. 3M makes a buffing compound in a black bottle, use it with a black waffel pad after you do the white (this removes the scratches from the white, do not mix buffing pads)
4. 3M makes a hand glaze and use it after #3 with a hand held microfiber towel. (this removes the scratches from the black)
For a Jeep steps 1 and 2 are plenty but if you want the best... buy this stuff at an auto body supply house, I can also get you exact part numbers if you like.
When we shoot for show quality, this is what we use to bring em alive.
