well when i worked at a bodyshop, norton came to us and showed us their products. i will be the first to say they were terrible. they had told us that their polish should only be used on freshly painted vehicles. well we had a 1970 Charger there, dark blue, that we were in the process of finsihing buffing. we told him to do a demo on the decklid, which was already sanded down with a da w/ 1500 then 2000, we were gonna do 3000 but he said they wouldnt need it. he first used the wool pad on a dewalt and then the foam pad and then finished up the the detailer spray, carried it into the sun and examined, sanding scratches everywhere. he asked how long ago it was painted and we said 2 weeks and he said that no wonder why b/c the paint had cured too much. i didnt like the products at all, i mean its a good idea but they need to do a lil more work on it
