Yesterday morning say my neighbor cleaning his 95 pearl white chev silverado truck. I noticed he wasn't washing the roof but was going over it with something in his hand. He said there were black specs all over the roof and turtle wax tar and bug remover wouldn't remove them so he had a brillo pad and was going over the roof. He said when he got through he noticed the paint was dull and didn't have any shine. Duh. What would be best to get the paint back in shape?
