Thanks guys, some really useful info there. I do actually have 2 gravity fed spray guns, not used them much; when I first started out I used them to spray the createx paint and was a little horrified by just how much paint they got through for not very good coverage, so I switched to a cheap airbrush which has produced a nice consistent colour finish (from my experience, of which I've had very little!) using considerably less paint. So I could go for these 2k urethane things but I know absoloutely nothing about them and cleaning the gun afterwards will be a nightmare (I'm quite lazy when it comes to boring things like that )
That Aeromax 2k stuff looked interesting, but a little on the expensive side I think (I guess you can't have it all) .. I don't know if the 2k urethane for sprayguns is any cheaper??
That Nitrocellulose stuff from reranch looks like the biz, it's in the sort of price range I'd be willing to pay for my first refinish attempt. I'm guessing I'd probably need about 4 cans of the stuff, only problem is it's in the US and I'm in the UK so I'll have to have a little look around for some equivalent Nitrocellulose stuff
The Minwax is nicely priced and is a poly ... might also be worth a look.
Maybe what I should do is shop around by a few cans of different types and brands within the price range and see which one I like the most.
