After putting my plane in the top of a tree I now have a few holes and tears. None are really major, though the biggest b1 is an inch by inch.
Problem is I'm having trouble getting covering to stick to it.
I've thought about monokote trim solvent.
I've tried a couple of times using a piece of covering off the bottom of my plane to patch the holes but it keeps coming off

If this is a glow plane make sure that the repair area is very very clean. Film won't stick to glow goo slimy film. I use simple green & alcohol. Also have used acetone washed down with alcohol. Windex does a decent job after either approach to really make sure that the surface is clean. Ya gotta get it clean.

I use Ultracote exclusively. Heat has worked fine on repairs like this. I've also played with Monokote's Trim Solvent too. TS makes the adhesive very tacky. Seems that it would work for a permanent non-heat fix. But it will dissolve the adhesive if you use too much.

BTW - round the corners on your patches - much less likely to pick up a corner later on.

You did not say if you have cleaned it real well. I will clean the area with ammonia first and then iron on my patches. Good Luck, Dave

also, be sure you're getting the Iron Hot enough? I always use a little extra heat around the seams and overlaps

I use Lacquer Thinner to clean and prep Film covering

good luck

Clean it with denatured alcohol or acetone at least 3 times using a new, clean paper towel each time

Thanks Guys, this is a gasoline plane. A Goldwing MX2 I'll try cleaning it again.
I'm using covering I robbed off the belly it was in an open area so I'm thinking the glue should still be good.

You may have trouble getting the covering to stick because the backing has been off for a while and the glue is no longer fresh...I depends how long its been since the backing has been off. I have tried this before with mixed results..Its best if you can use fresh covering...Good luck

One other thing, Trim Solvent does not work on every brand of covering. So if it's not covered in Monocote, the Trim Solvent wont help.

Yea - it works just fine on Ultracote's adhesive. Just make darn sure that you apply the trim where you want it 'cause it ain't coming off any time soon ...

Nope. Trim Solvent works on MonoKote but not Ultracote.

However, I have recently found that Xylene or Xylol will work on Ultracote

SeamusG

You be the judge.

Test setup - 4 pieces of scrap Ultracote
Seam 1 - orange over white marked H - heat @ 270 degrees
Seam 2 - orange over white marked Z - Xylene from ACE (phonetic error - oops)
Seam 3 - white over yellow marked TS - Trim Solvent

Test - clipped 24" GPsanding bar (no, the bar is NOTon the floor )

The 4th pic is with 2# of 180 G JHPbullets.

The TSbond failed at 4.5#. The film failed before either of the other two bonds failed. So, TS is weaker than either heat or Xylene.
