For Ed Selby on Finishing:
I'm not nearly finished with my LNC2, but it occurred to me that
while I've got it upside down for the last time it might be easier to put
the primer on the belly and wing carry through and horizontal stabilizer
lower surfaces than later on when it can't be flipped. The wings can be
done anytime in a cradle. I also painted the wheel wells with white epoxy.
It's a lot easier to apply the paint and do the sanding working with gravity
rather than the other way around. I used the recommended WLS primer and
brushed on the first two coats. All in all I've applied 4 coats, the latter
2 were sprayed on. I sanded with 180 and 400 grit paper on flat 20" boards
in between coats to get the really smooth surface I wanted, it was one hell
of a lot of work - maybe 35 hours or so of sanding alone, but the results
are glass smooth and without waves. I found there were some places where a
preparatory application of micro would have filled in some of the deeper
depressions a little more easily. I also think an air driven finishing
sander (on my wants list), one about 18 inches long would reduce sanding
time greatly. I avoided the orbital sander I have because I thought it
would be easy to introduce small localized depressions. Getting a smooth
surface that's continuous is important to sustain the boundary layer as far
back as is possible, and that's why I used flat boards. That was my
reasoning anyway, right or wrong. I felt a good smooth primer coat was an
essential foundation for the later layers of paint. I've thought about
flying in primer and etc. but haven't decided so I'll be interested to hear
from others about what has worked best for them. With regards to the
forum...
Cheers, Pete
