I'm wondering if the method of storage over all those years has an effect on the glue with MonoKote.
Kept it in the bedroom closet for lots of years and it still adhears when heated....Maybe I'm just blessed.
The stuff I have is really old and it seems to adhear well. I use it on planes that are smaller and it really still works well with me.
I still prefer coverite because of the way it stretches around corners.
Either way, I still keep a can of Balsa Rite on hand, just in case.....that stuff is really old too. It is getting thick and syrupy.....Maybe I ought to invest in a new can..........NAWWWWW!!
