I like the Meguiars range of products. Love the woolly mitt it is great to wash the car with. Don't have any trouble with the Megauirs chamios, must say the car comes up great. Also use a product called Mothers Back to Black on the dash, interior door panels and console. Also on any little bits of black trim , like around the windows, mud flaps etc the Mothers brings it up great. My problems are the windows can't ever get them smear free. Using Megauirs but still not great.
