I have a Perth Plus antenna in good working order, but the often found surface cracks. I'm thinking about a little JB weld for the larger cracks, a fine sanding & cleaning/surface prep followed by a few coats of black spray paint. Or possibly plasti-dip, just not sure how that will hold up in the long run exposed to the sun and elements.

Thoughts, ideas or experiences?

I have applied this one http://www.plastidip.pl/
Now my 24 years old Outbacker looks great

I may be wrong on this but, I believe JB Weld is an epoxy with finely dispersed metal particles in it.  Could that present a problem when used on an antenna?

No at all.
It works perfect.

JBweld epoxy is availabe with metal fill and without.
The metal filled version could affect the antenna if enough
was used but a few small spots not likely an issue.  I would
not use epoxy there because you really want flexibility.

the plastidip sounds good, with black spray paint.

Last time I encountered something like that I got a long
piece of glue filled (two layer) heat shrink. It flexes! 
Covered the whole length.  Worked fine so far (7 years).
