Thanks for all the info Stephen.
I have a 50ltr tank but only 9.5cfm, so I think I will put the auxiliary on. I might even investigate a low volume gun, mine are all a bit air hungry.
Thanks for sharing your thinking on lacquer too. Of course it makes sense to mask the stripe over lacquer too, in case of making a mess of it and having to go back a stage, that's going to be much easier over lacquer as opposed to base coat.
Come to think of it I don't have decals, but rather, reverse cut decals to be used as a mask or stencil, as it were. So the over lacquer technique could be a handy get out of jail free card.
Every days a school day as they say...Thanks again...
