I completly finished my IVP before I flew it.It seemed to me that there was
just too many negatives to flying it first in primer.Primer absorbs anything
that touches it and the only way to clean it is to sand it clean. You then have
to dissassemble the plane to paint it properly and then reassemble it after
painting. If you are confident that the plane was built properly there should be
no problems that could not be easily fixed. If you paint your plane with colors
that can be easily matched and blended then if you do have to fix something its
not that big of a deal. I have been in the car painting business for 37
years and have also painted several airplanes.

Gents,
I flew my 320 for a year in WLS primer. It was lightly sanded
and cleaned with MEK and Acetone before the final paint (Dupont base
coat,clear coat). The paint is still hanging on after 12 years.
Some notes:
I had large N numbers painted on the primer with Krylon - easily
removed with acetone. After cleaning and painting, the
Krylon left what appeared to be a raised area - that disappeared after
about 2 months.
Things shift over time. I can see the pre-preg weave in fluorescent
light - it cannot be seen in daylight. I have had a few pin holes
appear after 5 or 8 years.
It probably would have been wise to shoot on another coat of primer
before the final paint job.

Although it's a long way off, my
plan is to prime and then shoot a plain white top coat just to protect the
primer. I paint outdoors so between the bugs, pollen, and my
limited ability it won't be pretty but should last through test
flights and any tweaking. By that time the flaws that were mentioned will
hopefully show up and it can go to a paint shop for the final paint
job.
BTW on my Velocity project I found that
playing a heat gun lightly on the factory-primed glass would bring out
the weave. As I decided not to complete the plane I
don't know if there might've been a long-term effect on the glass or
the primer. I doubt it was any worse than a ramp on a hot sunny day though.
Might be something to try on some scrap... -Bill Wade

I also recommend flying in
primer. We flew my Legacy almost a year before paint. After
the first flights, we were up and down that wing hundreds of times fixing,
fiddling and adjusting many things in the cockpit and behind the panel
(many unusual body positions were observed I might add). Performing
the final fit on the glare shield in itself required many trips up and
down the wings. I think that we would have worn right through the
wing walk and paint!
