I'm building an EPP F-86 combat foamie with coroplast tail surfaces. I'm considering gluing small wooden dowels to the LE of the stabilizer and the fin both to make the LE more aerodynamic and to provide a heat-safe surface for attaching the Ultracote.

I could do the same for the TE, too, but I'm wondering whether this will improve the aerodynamics of the glider. I think I recall reading somewhere that the TE of tail surfaces should not be rounded as this can lead to flutter at high speeds.

Any suggestions?
