Without prep.. before any buffing polishing is a waste of time...your results come from good chemical clean and claybar.
Your zainos, megs are silicone based..These products hide alot of inperfections but the durability is short term..
I use a product called "Presta" which contains no fillers waxes or silicons...Results are outstanding..😎
Can I use white blackboard chalk to help remove grease stains from the interior - headliner and sun visor? My mechanic left a few dirty fingermarks behind.
