Hi Andrew,

I've been using this: Sign Mask Signmask Spandex Avery Dennison Light Blue 380mm EU 54876 A Print Sign

Works well, cant use solvent based rattle cans on it as its to thin and just shrinks/melts etc but water based no problem and maybe oil based.

I've only tried Rust-Oleum so could work ok with Plasti Kote, pics attached for you.

If you send the seller an offer he will do you a deal, think I got him down to £15 a roll for x5 rolls, good size rolls.
