Default Mylar aileron and flap seals

I'm just about to shoot paint (PPG Concept) on the Janus C wings after
months of stripping, profiling, priming, and sanding. I would prefer
NOT to apply any tape, including the mylar seals, for a month or two
after painting. I assume it will cost some performance, and I'm okay
with that. Is there a saftety of flight issue (like significant
degradation of aileron authority) likely to result from the un-sealed
ailerons/flaps? The airfoil is an FX-67-K-170 at the root to FX-67-
K-150 at the tip.

You're a STUD!!! Congrats on getting to where you are with this refinish!

The Zuni (& gobs of other 1st-generation glass ships, as you likely are aware)
nominally has the same 15% Wortmann airfoil at the root, Applebay-thinned (by
eyeball?) to 13% at the tip. I never bothered to seal my ailerons or flaps in
28 years of flying S/N 3 and never had any issues (that I could tell, wry
chuckle).

But you'd probably like to hear from actual Janus owners, I'm sure, given the
O-beer-thirty handling tales their appearance on the scene spawned! In any
event, my experience is this is one docile airfoil family.
