...I have a Iwata Revolution HP-TR1 and the silver jett compressor...

Nice gun/compressor... the 0.3mm needle is about right for TEMPTU's product line... albeit a bit out of my price range... lol  btw, used the silver jet in our local Glamour Shots in a production environment... this lit' workhorse takes a seven days a week beating gracefully...

I bought all the temptu s/b makeup--pretty much the whole line..

Excellent product, however not the easiest to learn on owing to it's high viscosity...  I suggest newbies begin with TEMPTU's Aqua line (water based) since it's seriously easier to master, enough said...

What do you run the psi at?

S/B? What exactly are you attempting to do with it? I typically need at least 14 to 18 psi with S/B but needle diameter plays into the mix... rather than worrying about numbers try getting use to the airflow on the delicate underside of your wrist... notice how it dimples the skin when you increase the pressure... you have to be rather careful about this working around the sensitive eye area, actually had a client yesterday complain it was tad uncomfortable when I was doing her ornate eye decor... it's a fine line between effective application and client discomfort.... even when experienced... would be wise to just do base i.e. foundation initially till you really get the feel of your gun/compressor combo... always check the airflow first on the wrist BEFORE doing close in work around the eyes... hope this makes sense...

Do I need to thin out the makeup?

Again, what are you attempting to achieve? I thin S/B with S/B mixing medium when doing fine work with my HP-C Plus (small diameter needle/nozzle) but not with my SP-35 for foundation...

I use 6-10 drops of the makeup but doesnt cover well..

Jodi I'm trying to be helpful here... you would be wise to get over the numbers thing... you are not selling a commodity are are selling an art-form... whatever it takes to meet/exceed client expectations is what you need... forget the drop numbers they are irrelevant... sometimes I use less than six drops other times dozens... whatever it takes...

...any pointers...

Once again, patience, practice and perseverance... it took me hundreds of hours to gain rudimentary competence with airbrush technique... the best advice? learn to listen to your gun, it will tell you exactly what it's doing... takes a while (read many, many hours here) but in time you understand what the gun is telling you... it's all about the "hiss" of the airstream, very subtle but yields a wealth of information...

Enjoy that HP-TR1...
