Re: [TowerTalk] Paint Fiberglass antennas?

[Grant Saviers <grants2@pacbell.net>]

Agree re boat painting, expensive and I'm told hard to work with, 
environment is critical.  Particularly Imron, particularly in my way 
back boating years.  Maybe easier now.
My polyurethane was standard single part on a Windsurfer mast.  It all 
flaked off.  Prepped with acetone.  I think adherence matters a lot on 
the resin in the surface - epoxy, polyester, polyvinyl, gel coat etc. 
some need primer coats IIRC.
