Don't use dawn! Like others have said it is designed for pots and pans, not your car. Adams strip wash is much safer and is great for removing old waxes and sealants
A touch less wash should have swirled the paint. Did you wipe the car down with a quick detailer very often? Mayne a bad microfiber or two could swirl the paint but I don't see a touch less wash doing it at all
I found that for headlights that are not as bad, the Adams microfiber polishing pad and heavy correction compound worked amazingly. No need to wet sand in this case
Is there a possibility of offering the strip wash in a gallon? I do a lot of car detailing and go through quite a bit of strip wash as well as clay, any possabaility of offering it in a gallon?
