Thanks for the tip. I never thought about using acetone as a thinner. I ended up covering the fuse with monokote today and it worked quite well. I'm using micafilm for the rest of the plane.

So I didn't do a very good job on researching the electric accessories for this little project since everything I bought, ESC, motor, and battery clearly mentions to keep away from water! Anyway, I'm aware of the hazards and I've chosen to continue. Fuse is covered along with both stabs and rudder. Main wing, wing floats, alerons and elevator left and she'll be ready for final assembly. Pictures soon!
