I live in Ohio so the temperature is always changing one day it’s 70 then the next it’s 32. But the only think I have done is waxed my vehicles. I’d like to know the best way to wash the exterior step by step using all the products that are recommended. Some of the cars don’t need paint corrected but if they didn’t need it would it hurt to put it on? I just want the best shine and protection. I’ve been really wanting to use the new ceramic paste wax, I’m more of a paste guy than the liquid waxes. But thank you guys so far with all the help.
