I used Duco in constructing my coils in 1967, vertical strips top to 
bottom spaced about 1/8-in apart 360 degrees around the coil 
circumference.  Forms were the Amphenol polystyrene type originally 
specified.  Coil windings in 2006 are as tight today as they were in 
1967, the magnet wire has not loosened at all, and the coils work just 
fine.  If you are having trouble with Duco today, the larger question 
might be chemical compatability of 2006 Duco formulation with whatever 
plastic constitutes your forms.
