Thanks for checking Daniel. The link that Jan posted has been helpful, but when I checked the kit on offer, I don't know if it HAS got extra nozzles! They're mentioned, but not shown, and I might have been getting confused with the 3 paint jars that are included. Not to worry, I've seen a semi-pro 'brush that I think will do the job, just waiting for an answer to my e-mail query.
That looks like a quality bit of kit Matt. Very nice buy, which should do some good work for you. Must try to find a similar one over here, as my old 'tin' razor saw has seen better days!
