Ah, ancient mold release... I think that was my downfall a few years ago with a new-in-box RT1601 Sherman I bought on eBay. It would not take any of the usual brands of tube styrene glue, and not CA either. I finally got decent results out of the Canadian-made version of Tenax-R made by MBS (Model Builder Supply) callesd APSC-1



If you already use this, you know its great stuff. If not, I'd suggest it, cause the mold release thats been absorved and contaminated the plastic might inhibit the penetrating and bonding action of standard tube glues, but it doesn't do it for the liquid stuff.

There is also the Plastruct brand Plastiweld (2 ounce / 56 ml bottle w/ cap-brush) , but often is more expensive per ml or ounce (it was in my local store) When I compared it on a price per ml, the MBS stuff was the best deal, but to use it the best way, you'll want to get one of the Touch-n-Flow sytrette applicators, and many hobby places don't carry them. I had to buy my pair off a US wholesale supplier who only sold them because he had no Canadian retail distributors! A pair for $15 shipped.

I've also seen the Tenax-R sets that come with one of these as part of a 'kit', and includes the Touch'n'Flow, some micro-brushes, and a needle-tube'd squeeze-bottle.



Google for " Touch-n-Flow applicator " and you'll find distributors online.
