This is the covering material I have and am planning to use: https://www.amazon.com/dp/B004ZB9HFO

I have never covered with tissue on a CL again after my grandmother put her hand through my outboard wing right before appearance judging at the 1964 NATS and cost me a place in the Walker flyoff.  Guess it psychological.  Get it on and get out to the circles while it is still Fall.  Best flying weather in the year.

Steve Berry:
That's my plan. Only kink in it is that the twins are coming (not your plane, my babies). Estimated birthdate is 10/10, with a possibility of sooner due to some outside circumstances. So, time is getting to be in short supply.

Jim Svitko:
I have never used polycrylic, and I rarely, if ever these days, build profiles.  That said, I prefer a wood-to-wood joint, no matter if profile or full fuselage.  Then finish.  It might not matter any, but I would rather not find out the hard way.

I make balsa fillets, sanded with paper wrapped around a piece of brass tubing.  Attach silkspan to bare wood with dope, overlapping the fuselage-wing fillet.  I never had a structural failure with this method.

Balsa fillets!  We may be the only two people in the world still doing that.

Dave_Trible:
Profiles are vibrators and known to stress crack at the wing/fuse joint unless well glued or epoxied.   I'd definitely prefer to do the wood to wood joint here and finish after.   That's the way I do them all anyway.
