Looking for some advice and input here-
Background:
My last chance to prep my last car for winter is this weekend, due to my personal schedule.
For perspective, it's a '02 Buick Regal (not a quick car to outside detail due to shape & body lines) that is parked outside but not driven a lot. It's been a year since it received 3 coats of Zaino z5/z2 and clearseal.
I'll have time tomorrow to only dawn wash and claybar. I may not have time on Sunday to buff (it needs it, but I can live with it until spring). Predicted max (which means morning and late day will be colder) outside temps will be in the 50s tomorrow and Sunday, overcast. The car is black, so the paint does heat up from the sun.
I have Zaino z2, z5, with accelerator, and Collinite 845 on hand. It's a given, from my experience on this car, that the Zaino at 50f ambient temperatures, even with accelerator, will streak if I try to rush multiple coats. I may only be able to put on 1 coat, followed by CS several hours later.
The Collinite would be a single coat. I've used CS over the 845 successfully in the past after a long wait.
Given the time constraints and low temperatures, which sealant would you choose?
