I agree you don't need the whole kit. Looking at tanning kits most use a bottle fed system (which to me still looks like the type you use for painting your house). I've never done airbrushing outside of the face however Iawata and Paasche both make some that would work for your needs. Since you have a Iawata compressor let's start with their airbrush gun first:
From Iawata:
Quote: This multi-purpose, high-paint-flow, high-detail Eclipse Series airbrush covers a wide range of uses. Commonly used to spray premixed or heavier paints, it is well suited for uses demanding precise control of spray when applying moderate-to-large amounts of paint to a variety of surfaces and to various-sized areas. This Eclipse Series brush has established a new benchmark for excellence in an all-purpose airbrush.
A unique “Pistol Grip†airbrush, the Eclipse G6 airbrush looks like a miniature spray gun, but sprays and performs like a large airbrush with its 0.6-mm stainless-steel nozzle.
· Equipped with a long tapered needle that ensures a smooth transition between fine-to-wide background spray
· Utilizes a dual-purpose air cap and a fan adjustment valve that lets the airbrush spray a round or oval pattern
· The round pattern is useful for painting graphics, while the oval shape creates a smooth background spray
· Uses a special fitting so airbrush bottles can be used instead of a gravity-feed cup, allowing for multiple color bottles to be interchanged quickly without having to clean a cup thoroughly – another unique feature for this type of spray unit – optional gravity-feed cups available
· Works well with the Iwata Studio Series Power Jet and Power Jet Lite Compressors
Iawata do have airbrush spray guns that are for more industrial use however from a tanning site they sell the G6. From a different tanning site they sell the Iawata HP-BCS however I think that gun leaves too much room for finger fatigue. It's good if you're doing body painting but not for tanning.
