I'm ready to start some priming of the micro, prepreg, and Aeropoxy/glass
layups. My local PPG dealer is not knowledgeable of such. I know that I need
to
start with an epoxy primer and then move to a urethane primer but am not
knowledgeable about the steps. Do I do a non -sandable epoxy primer first and
then immediately move to urethane primer before wet sanding or? Also I want to
spray silver topcoat but not do any buffing or polishing , so as to eliminate a
clear top coat. Is this realisitc? I'm in STL area where several high class
truck trailer painting booths are available. Ken

My 2 cents worth. I tried several primer systems and then found the
SITS POLYFIBER Waterbased polyurathane system. It eliminates the need for an
epoxy base, includes a UV protection, is odorless, nontoxic, fuelproof and
compatible with their topcoat, TopGloss, or Aerothane, or Imron, or most std auto
paints.
The primer is called SMOOTH PRIME, and can be ordered from Aircraft
Spruce, or directly from the supplier, I can give you a 1-800 #
You will need to fill major weave patterns and or glass defects with
thin micro first. sand to #220. then, the beauty of this stuff is that if you
ROLL on a couple of fairly thin coats and sand it until you think it is gone,
you will have FILLED THE PINHOLES. (a big deal). then spray on 2 or three
more coats, and sand to #320 and you are there.
A nice characteristic of this waterbased primer, is that for the first
5-7 days (depending on temperature), it is soft and easy to sand. Then it
starts getting harder and harder.
Spraying on a metallic silver top coat is another matter. My paint
friends tell me that this is the hardest thing to do, because getting even
dispersment of the metalic fragments requires a high degree of skill. If you get
everything nicely primed, A little professional help with the topcoat might be
in order. LRE
