This might be old news for some. Louis Rankin taught me this.
Get some modeling clay and roll a coil along the edge of the monokote next to the joint. It acts as a heat sink. The clay will liquidate a little but the monokote does not curl up. Just be sure to iron the edge down first.

I’m confused. What’s the purpose of this??

To use up the clay around the house so that the kids aren't smearing it on the walls?

Acts as a heat shield to keep the monokote from curling up at the edge.

Thanks Paul, I'll give it a try on my soon to be performed repair! Missed you at the Brodak FlyIn. We had a great time for the first three days. Couldn't afford to stay the entire week this time!

Don't you have some extending over the edge so you can iron it down? I usually have about 1/2" ironed on the edge and seal that so fuel doesn't get under it.

Hey Phil
I really wished I could have made it up. It’s a two day drive for me now that we moved farther south. I miss seeing all the gang. I hope it happens next year. 😉

This is right against the fuselage. Iron it down with a trim iron, lay the clay down and hit it with the heat gun. The covering will not roll up if you get too much heat next to the fuselage.

Great Idea. I will try it. Nothing can compare to the overwhelming sense of doom as you watch one of the edges come loose and curl up before you can move the gun. I monokote my fuselages as well and I do the fillets separately first with about a 1/2" overlap on both the wing and fuselage. I sand the edges then go for the wing. If you don't get the edges sealed really well before going to the gun you are going to have a mess.

Wing to fuselage joint, apply the monokote 1/8 from the fuselage then put the fillet over the monokote and paint the fillet.

i use a wood ( usually 1/32 plywood) piece to protect the 1/2" lip of the monokote ( ironed with the trim iron, very hot) close to the fuselage. This makes the heat flow towards the tip and let the glued edge undisturbed.
then i apply white primer over the covering, sand, and overlap with the final color about 1/2 over the ironed edge.
