Yeah, i dont use water as a thinner for acrylics, not even when brush painting. Cheers for the answers guys, although it would be good to hear from the OP as i have hijacked his thread a bit.

Dads203 - Thanks for the reply. I think your right in that i need to experiment with the thinners etc and i will look to get some Mr Color leveling thinners soon. cheers Jon

I also have a Sparmax 4 along with a Sparmax Arism Mini compressor, and have experienced the same problems as the OP. I use it as dual action and have a silver bullet fitted. I have found that i needed to thin AK/Mig paints to get a better flow but am still struggling with Tamiya which leave a rough dusty finish, which i think is the paint drying on its way to the model. I thin with UMP thinner but have some x20-a on the way. Funny thing is that UMP primer flows fine and apart from a bit of dry tip i get no probs.
