I clayed my car about 4 days ago then put a generic cleaner wax and carnuba on it. question is]My car had such amount of crap stuck to the paint that when I was claying it was turning the lube reddish brown and the clay itself was becoming black in about 10 swipes. A detailer freind of mine said to use quick detail spray to lube it, while I was using a bottle of megs car wash and water and spraying it, I also was hosing down the area immediately with water to flush away.According to the detail nut whose car I had just fixed, I was not supposed to use car shampoo, is there any science behind it - because he couldnt answer and I believe the lot here is far more sensible.btw - cheap chinese blue clay was used, got it for USD 5/- for 220 grams bar. It really cleaned the paint work though.
