Gollywok could you tell jim what size needle and fluid tip set up you are running,same model sprayguns come in many different tip sizes and model numbers the fluid tip size is engraved on it's side.Just remove the aircap and look for it.

Hi jim,doesn't matter what you spray,thin it appropriately and experiment a bit.Re thinning,when you finish stirring the mixed primer/colour and prior to pouring it into the spraygun pot,lift the stirring stick up quickly and watch how the drops run off it,you'll be amazed at how quickly you can gauge the viscosity and how well that material will go thru the spraygun tip in comparison to what you have mixed and tried just before.I'm not familiar with the badger but i may use it under another brand name.In general terms we automotive spraypainters use a conventional 1.2 to 1.4mm suction cup or gravity fed spraygun for most things and air pressure between 35 and 70 psi depending on the job,a foot wide fan and a foot back from the surface.Gollwok's description has me thinking it's a small touchup gun and anywhere from 10psi and up on them,at 35psi you may as well use a bigger gun.Try varying the distance between the tip and the job,also the speed and number of passes with the gun.For a start you could practice holding the gun at 90% to the surface you wish to spray and then moving it back and forth smoothly while maintaining the same tip to job dimensions.When you pour the paint in it gets harder because now it's for real and you're more nervous,have a test panel set to one side so you can get up a good rythym and then start spraying OR you could wait a bit(around five minutes)to see if what you just sprayed is going to head for the floor.Around 25c is a good temp to spray at,things get proggresively harder the further you go each way temp wise.Read the paint instructions(tech data sheet/msds) You need to develop a good rythym,depth perception and feel,just like flying and that comes with practice.High velocity low pressure(hvlp)guns are good at home or in a confined space,far less overspray.They are far more efficient re atomization but for the size you paint there's no difference in material savings and they are usually lot's dearer to buy.
