A roll of clear application tape ( which is what I use) @610mm wide X 100 metres will cost around $90 from a sign supply company

Jezza that's a good price, I'd never need to buy any ever again.
I haven't used Frisket but from what I've been reading it appears that it will make life a little easier with the KoS playfield restore. It's a funny thing painting playfieds, it's probably the most fun and the least fun thing I've done to a machine. Parts of the process are dull and time consuming but it's very satisfying when things turn out as hoped which doesn't always happen for me. It's been very much trial and error, all in all enjoyable though.
