If you’re
going to fly in primer, I would advise a sealer coat over the primer.

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.

Re: Fly in primer?
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.
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

Re: Fly in primer?
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!
Fly safe,
