OT -- POR15 and UV stability

["nruff" <nruffcorn@prodigy.net>]

Hey all-

Like many of you, I have coated my roadster frame with gloss black POR15.
The can warns against instability if the product isn't topcoated and exposed
to UV light.  They recommend their "Chassis Black"  as a top-coat.  At
$37/quart, they can forget it!

Have those of you that have used this product had any ill effects from not
topcoating?  I can't imagine the frame getting many UV rays anyway?!  Let me
know what you think.
