Hey guys! So I`m living in Arizona and we are getting consistent triple digit days now for the summer. I just coated my WRX with CQUK 3.0. Before this I have used 22ple HPC and Gyeon Pure. Every coating has been great but I have one problem here in Arizona I have never been able to remedy. If I get hit by sprinklers, rain, bird crap, or anything wet; due to the heat and how fast it evaporates, I`ll get water spots or some form of etching. I know all Si02 protectants carry this added risk but is switching to collinite 845, fk1000, or power lock going to be any better of an option? The way I`ve seen it so I dont go crazy, is that the etching is on the coating because it always buffs right off with a light polish when I re apply coating every 1-2 years. I`m wondering if anyone who lives in similar climates or knows if spending 200+ dollars on a new graphene coating or other sealant/wax is a better option? Any opinions are appreciated! Thanks guys
