I will be polishing my friends '01 black vw gti in about a week or so and i just ordered some products. I got some Optimum Polish along with Wolfgang glaze. I will clay the car down first and then use the glaze on the entire car (wIll the glaze remove some scratch marks? I nopticed he had some on the roof), and then do an IPA wipedown and apply some Wolfgang Glaze and then Apply some P21S carnauba wax. Can i apply 2 or more coats of carnauba wax? Anyways, let me know if this sounds right to you guys. Has anyone had experience with both of these on one car?
