If mattcote's anything like the old humbrol matt varnish, it takes a SHEDLOAD longer than any other paint to mix properly so could be that...other than that i dunno what's up with it!!

It finally went matt, but as you say the bottle needs to be stirred/shaken like crazy. In fact, I ended up putting a twisted length of fuse wire into my Dremel-clone and using it as a stirrer - that did the trick! The gunk at the bottom was like treacle (not the same colour thank goodness).

Jus for my own info can I ask what proportion of white spirit/thinner to paint you use when using enamels? I was spraying my brother's boat humbrol gloss yellow and it seemed to be flying all over the place when it hits the surface of the boat!

Is this caused by too much pressure (I just use enough to get a sedate spray pattern) or have I made the mix too thin??? (about 1:1 with white spirit) I don't actually think I've ever sprayed gloss enamel so maybe I'm doin something totally daft!

It's all primed and everything so I dunno what I'm doing wrong!!

I must tell you that I am a relative beginner at this airbrush lark. However, there was a distinct difference between how Humbrol went on, and how Revell went on. Revell was much more "watery" and did not need much thinner at all. Humbrol was thicker and did. All the hints pages I've read on many websites says to mix it the consistency of milk.

From what you say, I think you've made the mix too thin. 1:1 sounds too much. Make sure the yellow is well mixed in the tin before decanting it to another container and mixing in the thinner. Dip a cocktail stick in a tap it against the side; the fluid should run down the side like milk.

Keep the pressure to about 18 psi and don't get too close - lots of thin layers is better then one thick.

Good luck.

Yeah it does seem to be thinner than milk, I'll probably make the next batch a bit thicker even though I'll probably need more paint, it's important to get the job done right!

Will let you know how I get on, thanks
