Estes Thor Agena Build Part 25 Tunnel Sealing

All the basswood pieces - tunnels, antennas and vernier nozzle housings - get sealed with clear varnish. You could use sanding sealer or dope.

I don't get too fancy with this, most all of it gets sanded off anyway.
I dip a paper towel into the varnish and rub it over the surface. Try to keep the varnish off the flat gluing sides.

After you're done, throw away the paper towel. No brushes to clean.


Sand smooth with 400 grit sandpaper.
This varnish will load up your sandpaper to it'll probably get tossed, too.

Two coats are needed for a good sealing.
Sand between both coats.
