The problem is that before i got the car,they polished it by rotary polisher creating heavy swirl marks.They tried again and again to repair them (by rotary polisher again) and they made it worse.Since then (3 years ago) i was trying to repair the paint by hand polishes, swirl remover,glazes etc.I tried Autoglym super resin polish,Autoglym deep shine,Meguiars scratch-X without any results.Then i bought the Ultimate Detailing machine and i tried it using the scratch-X on the white pad(SFX-2 SonusPad) and to be honest i saw big difference.Because i am not sure about the clear coat's level(because of the "professional" detailer) and because of my experiments, i don't know what to do.Now i have in my "collection" the UDM Polisher,the 3 steps of SFX Polish,the Meguiars scratch-X, the Meguiars paint cleanser(step 1) and polish (step 2),the Klasse-All-in-One.the Klasse glaze,carnauba wax,the SFX pads(steps SFX-1,SFX-2,SFX-3 Pads),the DAS Pads (white,orange green and blue),the Sonus swirlbuster polish and the Sonus paint cleanser.Please tell me if you can what is the better and safer way to combine those products (i mean the best combination, not all of them : ) ) to have the best possible results.
