CURING POR 15

I've had great luck with POR-15 and Chassis Saver. Like anything coating preparation, preparation, preparation. I use it on frames I can't get it off without a lot of work.
I live in the dry desert and it cures over night here. I have some vehicles that I used it on years ago and after several winters of driving it is still on tight. I think it is great when used correctly. It doesn't like sunlight though.
