Thanks, the paint is Mig Ammo, MIG 901, 902, 903 & 904 - all Dg shades from Dark Base to High Light - you can get them in a set for little under £9 (if you're in the UK I've had excellent service from SandM stuff - careful how you Google that one). There's also a hard line highlight on some parts, also Mig, MIG 012 Dunkelgelb aus 44 DG III.
I'm thinking of doing a late hard edged three colour camo of the Daimler - Benz factory type so I'm looking for something to make the masks with. I've used tape & white-tak in the past but never been entirely happy with either, so I plan to get hold of some Panzer Putty or the PK Pro equivalent, so if anyone's had any experience with the stuff I'd love to know what you think of it.
