What paint for chassis parts?

[Ameer Antar]

I agree, I think POR-15 is the best. & there are tons of people, esp. 
restorers. The only thing I worry about is the UV sensitivity. It's not a 
big deal on rusty a/c's, but what about on a car subframe which gets 
hammered with stones and debris, esp. where I live, just around the 
block...Couldn't this chip the overcoat and expose those parts to UV, 
destroying the POR15? What do you think of this issue?
