vinyl for masking shell?

[carlukemini]

Hi All,

Wanting to paint some basic two or three colour designs on lexan shells. I've seen folks using vinyl to make masks up, but I wondered what people were using and where they got it from. I have some vinyl at work for sign making, which I have made window masks from in the past, but when peeling it left a fair bit of residue.

Not aiming for anything top ambitious, just maybe a basic flame design for example.

Thanks for any info,
Craig
