Heuge,
To help you in your searches. Try searching for DACP, SFP, Diamond Cut, SMR. That should get you a tonne of information and help you out.
To help you out, we'll need some additional information:
1. What is your current wash procedure (products, methods, wash mitt (cotton, sheepskin, brush etc.)?
2. What is drying technique.
3. Towels? Microfiber or 100% cotton or something else?
Generally, it's accept that
Meguiars Body Shop line and Professional line's are very top grade and so are 3M Perfect III line. There's a couple of new guys that are producing some very interesting products (Poorboy and Clearkote).
The biggest way to deal with Swirls is to try avoid getting them in the first place. Which means, very careful washing (2 bucket method). Microfiber or only 100% USA Made cotton is the way to go.
Anyway, read through the searched threads and you'll be amazed at the amount of information here!
