Fuselage Skin Priming

Catching up on a few pictures from the last few days:  I bolted/torqued the control stick bases to the aft center section


The front center section has 4 "cover support" ribs that get attached to the front side.  My best guess is that these are what the flooring under the seats wraps around and attaches to.  Each rib gets 3 large holes (all different size) drilled into them for fuel lines, brake lines, and electrical routing.



That brings me to today.  The weather looked like it would hold out, so I decided to prime all of the fuselage skins.  Everything that isn't visible in the cockpit I primed with the same Ekoprime I've always used.  For the side skins, floor skins, and fore most upper skin in the tail cone that extends into the baggage compartment, I used Ekopoxy.  This is a 2 part epoxy primer that is supposedly quite a bit tougher than the Ekoprime.  I figure if it's tough enough, I can probably get away without painting the cockpit interior.  Most of the cockpit will be covered with carpet and wall coverings anyway, so very little will be visible.  I ordered the company's next lighter grey shade, thinking the light color would help make the cockpit seem a little bigger.  It's far lighter than I thought it would be, but it'll be fine once most of it's all covered up.  I definitely prefer shooting the regular Ekoprime.  It's far easier.  The epoxy has to be mixed with a catalyst and water, and it is still fairly thick to shoot.  I used a larger tip on the spray gun, but I still had trouble with it clogging.  I'm not sure how even the primer ended up laying down.  I can't really tell until it's dry.
