My long range diagnosis was indeed correct. That’s a weird thing to happen though - what glue did you use? It almost sounds like heat damage to me, rather than glue damage, especially the way the parts have curled apart.
As an expert kit burner in my youth, that’s the sort of effect you’d get it you brought a not-so-well-glued wing towards a flame… believe me - I know! [;)]
Yes it definitely looks like heat damage, but there was no sourse of heat near it.
I used Revell’s liquid cement. Its like testors or Tamiya’s brush on cements only a bit more syrupy in consistency and faster setting.
Well thankyou very much- I have now learnt more modelling tips.
Watch thin trailing edges- use cyano or epoxy.
Don’t use cellulose based filler on vacform kits.
Roughly cut out vacform parts, and sand the bejesus out of it back to the correct profile.
And one mans disaster is another mans lesson…thanks!

I know the stuff - I have a bottle of it with a little metal applicator tube. I’ve not used it much, and I don’t think I will again! Sounds way too scary to be waving about near my precious kits [;)]
How’s the repair to your vacformed bit coming along? Didn’t you say you picked the kit up in the bargain bin? Correct me if I’m talking out my a** here. If it was, it could have been the age of the plastic. Some plastics get brittle over time, so that might explain your catastrophe. If you take it nice & slow on the rest of the cut outs you should be ok [8D]
When you build the perfect model, quit! Otherwise, just keep at it and treat each model as a learning experience. Most vacuform kits are made from very soft plastic (PVC) and styreen cement will melt it quite easily. Try some other types of glue, like epoxy . Liquid glues that flash very quickly, like Tanex 7 or Weld-On #1, #2, or #3 can be used as long as you apply it sparingly. It should set up before it has a chance to melt the surrounding area.
Also, try sanding the vacuum formed piece on a flat surface of 220 or 360 grit wet/dry sandpaper (wet). Before yo do this it is best to do some scale measurements in order to determine if the thickness of the sheet of plastic should, or should not, be part of the piece. If the thickness of the sheet of plastic should not be part of the piece you can sand the piece until the plastic is paper thin, and then cut out the piece with a sharp Exacto blade. Vacuum formed kits are a real challenge.
Is there no way for you to call whatever company it is and order a new wing, or is this not an option? Hope things look up for you!
Curing glues often build up heat-so it could be a solvent/heat problem. Next time you mix up a 2 part epoxy-hold the container just before the epoxy sets-it gets hot!
whatever does not kill us makes us stonger. sorry to hear about your problems, it’s frustrating but keep at it.
