i washed and waxed my car on friday. i only applied on coat of meguiars gold class on the body and three coats on the hood. the hood is looks very good but the rest of the car looks alright. im gonna wash it and wax it again tomorrow and just wanted to know how long should i let the wax sit before wiping it off and is it ok if i wipe it off with a cotton towel and not a microfiber towel.
