Hello, I intend to treat my recently acquired TT,which I waxed 2 times with the 476 s,something else,I think of Meguiar’s products Now to my question,..should I wash the box with rinsing water,to get the whole old wax down,to then switch to something else,..or can I simply apply the new wax to the old one,though rather not,or? Sorry for my naive question,I have never really dealt with the car care,thesw egen I hope for a few profit tips,.. many thanks in advance
