Removable masking paint/coating for chrome plating of plastic

.

Does anyone know about some kind of masking paint/coating which can be removed after plating? I need to plate some plastic parts and need some kind of masking which is easily removed afterwards.

What type of plastic are you using? There are some maskants available for chrome plating but most of them contain solvents that will attack plastic. ABS plastic is more resistant to the attack of some solvents.

Currently, we use epoxy paint to insulate the part of item we do not want to plate. Sometimes, we can also use polystyrene plastic melted in M-3 solvent.

However, these insulators are difficult to take off after plating.

Anyone has better method ?
