I was thinking about getting my 2019 RAM Rebel ceramic coated. HERE is the question. Why is it, that one dealer charges $12-1300 while another charges $450?? Is there that much difference in costs involved in applying ceramic coatings? Also...I live in Florida where it books in a cool and crisp 95 degrees with sweltering humidity. I have a mobile service, ($1200), that will come to me...do paint correction...and apply coating...but doesnt the heat affect the results? Is $1,200 fair..or is it insane? I have so many questions.
