Quest Raptor Build Part 7, Fin Primer and Gluing

The fin pieces will get a primer coat off the model.

The gluing edges were taped off to leave naked balsa for a better gluing area.

Here's how the pieces were taped flat for grey primer spraying.

All the balsa pieces were lightly stuck down on some masking tape, sticky side up.

The primer was shot and all pieces sanded with 400 grit.

I screwed up here!
The larger wing "pads" are glued from one side to the other. The mask strip is long.
The smaller fins are only glued on the center area of the pads.
I masked the small fins like the larger fins.

I ended up flipping the mask line side to the outside figuring this masked strip would be better filled after gluing the pad in place.

On the wings, the interlocking tab was a little taller than the thickness of the pad piece.
I removed the pad, and sanded down the wing tab slightly.
The inset picture shows the tab even with the pad surface.
