A clay bar is an awesome detailing tool. It’s by far the best way to remove bonded contamination from automotive paint. This FAQ covers most of the beginner questions I see in online.
I love the way my paint feels after I have used a clay bar. I have tried and tested many different types and my research will help you avoid mistakes I made.
Clay bars can cause paint marring which can be difficult to avoid. Also known as scuffing or micro scratching. But you can keep this to a minimum by following the tips.
- Your car should be freshly washed.
- You should use plenty of lubrication.
- You should use side-to-side motions.
- You should not use too much pressure.
- Don’t panic if you cause micro scratches. They will buff out.
The most important thing to remember when buying a clay bar is to get one from a well known manufacturer and not some cheap product from a company you’ve never heard of.
Also, for relatively new cars I would recommend a fine clay bar and always use plenty of lubrication.
Only older cars need heavy duty clay bars. You’ll almost always notice scratches after using a heavy duty bar so polishing afterwards could be needed.
Clay bars have a lot of myths and untruths associated with them. But the truth is actually very simple. I hope this FAQ will help you out.
