<font color="336633">Welcome to TrainBoard! I have never used it before as I dont think we can get it this side of the pond..... What type of glue is it? and what type of materials has been glued.</font>
Not certain which type of Testors glue you've used. But if it's on a model, removal could be difficult. What you might do, is take some scrap materials of the same kind the glue is on, and experiment. Be sure not to breathe fumes! Boxcab E50
Were it ACC (super glue), I'd recommend nail polish remover- the acetone contained therein works to dissolve the cyanoacrylate in super glue. No idea what to use on Testors cement, but perhaps the nail polish remover could work. Hey, worth a shot.....
Was this the liquid cement? Or the stuff that comes in a tube? It may not matter. With trying to remove, for any solvent chosen, you will need to be very careful that the plastic of the shell is not attacked. I'm afraid that if the unit is already painted, you may end up needing to do a little gentle sanding, and repaint at least that area. Boxcab E50
Testor's cement for plastic is similar to MEK and has a bit of melted styrene in it for body. It tends to melt the parent plastic to make a tear bond. Sanding is about all that will remove it from the outside, like a run or drip. Whatever was cemented onto the shell is now a part of the shell, so there is no "glue" between two separate surfaces. That was their selling point when it came out: "Seamless plastic welding". It was made for the scale model airplanes that were shelf models. If you work with it all day long, you will be feeling pretty high by supper time, don't try to ride your bike home!
