I just finished PPCL and will start AIO in three days on garaged car. Should I Gold Class wash prior to first coat of AIO application or just AIO over 3 day old PPCL? Thanx.
You can AIO right over PPCL as long as you've buffed off the PPCL residue. PPCL is a great prep and should not need to be washed. AIO will clean any extra residue you don't get to.
Since the car will be sitting in a garage for 3 days you don't have to wash but I'd recommend QDing the car to get the dust off of it before going to AIO. I'd personally QD each panel right before using AIO but that's just my preference.
