I am preparing to "re-do" our Dark Bowling Green Corvette this long weekend and want to ask the experts opinion. I plan on going over the entire car with #9, then #7, and finish with NXT. I have read some people put #7 on top of NXT (or Gold Class or 26 - your choice). To me this seems like a waste - would the #7 penetrate the wax or sealant? What would be the benefit in doing it in this order?
