i used to always use gold class car wash, because i had a lot of it (64 oz). the other day i bought a 64 oz. of NXT wash, and i finally washed my car with it today. for some reason, it looked 10x better. at first i thought it was juar because of the clear corners i added, but it looked better all around. is there somethign special in NXT wash that GC doesnt have???
