I have tried them all. I use strictly Adams Detailing Supplies. I use Flex and Porter Cable .. Adams is 100% USA. It is safe. If you ever get on You Tube check out the Junk Man Detailing Videos.. That is where I got Adams from. Used Zaino prior and Pinnacle and Wolfgang. The Pinnacle Souveran Wax is really good, matter of fact GREAT. But since I switched to Adams, so much better. You are right,, everyone thinks some products are better than others. Since I love machine polishing, could not find a easier and better products to use.

Yes Dawn will strip it down for the most part. But if you strip it down, wax is a must. Nothing Like a baby butt smooth paint surface to polish down. A machine sealant,, 12 hours later a good wax and then a coat of Brillant Glaze. No better shine.
Back to the bugs.. clean and clean and then clean them again...
