E’Tac Clearance Sale! – 50% off all current stock!

All stock is in good condition with a few items that have water damage to labels from our last big rain event. We believe E’Tac to be one of the best water based mediums ever made, after struggling with special formulas (not safe btw!) to get other brands to spray, E’Tac was the only one to spray out of the bottle with great coverage and bright colours!
It’s a shame it’s not more popular in Aus. but it’s not moving off the shelves. We have most colours in stock of 2oz and 4oz with a few 8oz and 16oz of black and white. If you’re keen to buy up big feel free to contact me for a package deal, everything must go!

Product Details

Brand: Grex

Compatible with all brands and types of airbrushes, giving you the freedom to put airflow control on any of your airbrushes, instead of being restricted to a specific airbrush.

Comes as a quick connect air coupler allowing you to easily switch between airbrushes to give every airbrush the ability to control airflow.

Attaches to the air inlet of your airbrush. This provides better balance compared to having the airflow control below the head of the airbrush. You also don't have to worry about accidentally moving the head of the airbrush while you're simultaneoulsy adjusting pressure and spraying.

Designed with a large dial to allow easy air pressure adjustments. This is particularly helpful when spraying and adjusting air pressures simultaneously.

Capable of achieving fine adjustments to give precise air flow control. Three full dial rotations to change from zero air flow to full air flow.

Ideal for stippling applications. Accurately control stippling size while you're painting real-time. With a simple turn of the dial, the G-MAC™ gives you the ability to produce course stippling effects to full atomization.

For fine lines and detailed work, use the G-MAC™ to precisely produce optimal airflow for infinite control of paint output.

Fully open the G-MAC™ to allow maximum air flow for wide background spraying and to quickly clean your airbrush during color changes.

* Versions available for Badger and Paasche on request.
