Masking machined parts using vinyl

[Brookway]

Our company has been using standard paint masking tape and exacto knifes for precision masking. The parts we are masking are aluminum investment castings that have been machined. In an effort to reduce our masking time we have decided to purchased a Roland STIKA Series Vinyl Cutter Model SV-12 (12").

All of our parts require Polane-T paint and are cured at approx. 300 deg for an hour or so.

Does anybody know what vinyl type paint masking would work well for both the cutter type and paint type? If so, would you have information on a good source to purchase?

Thanks for your help.
