Buffing Streaks

The correct way to fix swirl marls is to use the correct products from the beginning. Swirls marls are from to aggressive of a compound and/or pad and not keeping it flat. Heavy cut compounds and wool pads cut fast but leave the paint hazy. Its just like sanding. If you start with 80 grit (heavy compound and a wool pad) you can finish it with 600 grit and expect it to look good (Glaze and a blue pad)

The best thing you can do to improve your results is replace you buffer if your using an rotary. They were developed for grinding, not for polishing paint. Professional detailing buffers are dual action. I use a Rupes but they arent cheap at $400. Porter Cable makes a much cheaper D/A that is easy to use and still does a good job.

Also, buy your self some foam pads. Lake Country are the most popular. Get an assortment Yellow, Orange, White and Blue. Or you can order a Hex Logic kit from Chemical Guys.

For compound and polishes I use Meguiars. 105 and 205 are very common in most high end detail shops. I also like the D300 which is designed for microfiber pads.

In your case I would seeing the car is already compounded I would start with an orange pad and the 205, then follow that up with a white pad and the 205. The idea is to get the paint as nice as possible before wax. Wax shouldnt be used to hide anything. I actually no longer use waxes in my shop, Everything is sealants.

Heres a good kit to get you started
