You wind the regulator in to increase and out to decrease.

Ooops sorry mustve missed that post. Thanks for the tip, but i thought that mixing acrylic with lacquer caused it do coagulate in the brush? Just to clarify mr colour or mr hobby thinner? I really want to invest in some more of their products but its confusing the way they market their stuff. Judging by your results #1 is the consistency i need.

Some acrylics (e.g. Citadel Paints) do not respond well to lacquer thinners so always test a small amount. I used Mr Color (lacquer) thinners in the test. Mr Hobby (Acrylic) thinners does not seem to be the same as Tamiya X20A thinners so I can't recommend using them with Vallejo paints. Tamiya X20A thinners will be a good all rounder acrylic thinner to have on hand along with Tamiya Lacquer thinners which perform similarly to Mr Color thinners.

Ok thanks for the tips guys, the vallejo/mr colour thinner is the desired coverage im after. Like you say though i might practice on the back of some disposable spoons.

Some people like to put cotton inside the moister trap (glass vial) to absorb moisture, I don't personally do this.

There should be a bleed valve at the bottom of the moister trap to control the psi. Check for something that is easy to unscrew.

The white cylinder with the black bottom inside the glass should be a paper filter. The whole thing is a moisture trap but it doesn't look as if it has a regulator unless those half circles visible on the top are buttons of some sort. As that compressor doesn't have a tank you will always get some sort of problem with consistent airflow. The bit sticking down below the glass should be a drain for the moisture trap.

That's not a pressure regulator that will just let air vent out the bottom.

Damn, I was looking at buying that particular compressor from http://www.hobbytools.com.au/sparmax-ac100-super-quiet-air-compressor/  but now I'm not too sure.

Im guessing you might be able to regulate the pressure with the bleed valve somehow? looks like their are multiple hex heads, maybe tweak one to see if it doesnt affect it puddincup.

Since there is no regulator in series with the moisture trap then there should be a bleed off valve on the moisture trap. A bleed off valve can control the output psi.
