Can you explain why every other car here in California and Nevada has the clear coat falling off after only a short time? Even high end cars. I thought sunlight was the enemy of clear coat? Fungus growth underneath and all that.I owned a paint and body shop for a while, so forgive me if I skew things.
First, if it is going to sit in the sun for any length of time, I would 100% clearcoat it. It is an easy thing to do and the benefits far outweigh any downsides.
I would never use the stuff in this environment.
