Yup, sometimes you just can't waste a good one. That's why I decided to redo the Gladiator (don't ask) just too nice to leave sidelined.
Bill, if you apply some heat to a joint and lift the edge with an Exacto or some such, then get a hold of it with some pliers at first to keep from burning your fingers. The then work the heat back and forth over the area where its lifting off. If you lift just enough to start lifting the model and play the heat, the M'kote will come off pretty clean by the weight of the model alone.
I've got my Ultracoated Nobler I'm so embarrased of, 2 flights on it, it may get this treatment yet too.
