Coil dope is polystyrene plastic dissolved in methyl ethyl ketone.  
When the solvent evaporates, you basically have a coating of  
polystyrene plastic. Glyptal is an alkyd-resin based enamel paint (aka  
oil paint). When they solvent evaporates, you have a coating of  
(pigmented) alkyd resin, which then crosslinks under exposure to  
oxygen into a touch coating.

GC Electronics part number 10-9002 "Red Insulating Varnish". You can  
order it direct from GC Electronics's web-site, or from most  
distributors who stock GC Electronics chemicals.

It looks to be identical to Glyptal Inc. #1201 GLYPTAL Red Enamel paint.

Best regards,
