I have some Danase Paint Sealant. I also have 845. If I was to apply 2 coats of sealant 8 - 12 hours apart, come back in 12 hours and apply 845, you that be overkill? I was thinking on just using the sealant for the winter months, as I wax the car every 2 weeks in nice weather? Would I SEE any difference in look with the two? Anyone done this?
