So i was wondering how i was going to pull this off without holding onto their cars overnight. My plan for the winter was to apply WG pant sealant and then top it off with Collinite 845. Problem is the WG needs 12hrs to cure before i can top it off with #845. Am i correct with the 12 hour curing time thing or have ive been doing it wrong this whole time? Im an at home detailer part-time and don't own a shop, so i was thinking of having them bring it to me the next day, leave it over-night or i would come out to them. Just wondering what your guys inputs or suggestions are.
