Good stuff. I tape my fins upright on a piece of chip-board (tape the root of the fin (on both sides) where the fillet will go so that it doesn't get painted or filled) and spray away. Two coats, then sand. And again. I do this before I attach the fins to the body. Works wellfor me.snip...DEFT (lacquer) spray sanding sealer-I get it at Lowes--

NO!!! --Pre stain is made so the wood--what ever type will accept stain more readily. Don't do it--esp on balsa--Sanding sealer , drys and shrinks the pores of wood as well as acting as a solid medium or filler--I have started using DEFT--spray sanding sealer-I get it at Lowes--It's laquer based and drys quickly---water base has the potential to warp fins and swell them---note---always apply any liquid on wood on both sides if you do not want warpage--or at least minimal warpage---esp -thin stuff
How the heck do you get it inside of a 54mm Blue Tube airframe (and do you even attempt to sand it on the inside?!)?
Did not know about that product. Then again, is something like a 55 mile round trip to a Lowe's.DEFT--spray sanding sealer-I get it at Lowes--It's laquer based and drys quickly
If you're into old timer aircraft at all, nitrate or butyrate dope works well as a sanding sealer too.
One can gets me through about two of my builds--if you've seen them they are something like--ALL WOOD--So a couple of cans should last you at least a season if not two--worth the drive. Heck, that's my round trip to work every day. Did I mention I hate my job??Did not know about that product. Then again, is something like a 55 mile round trip to a Lowe's.
