The Army Painter Airbrush Primer Matt Black, 100ml Dropper Bottle Acrylic Paint Primer for Airbrushing and Painting Wargaming Miniatures, Perfect for Tabletop Boardgames

Tried using it for priming PLA prints. I thought it is good initially, but after drying I was able to wipe it away with my finger. Not really suitable, unless you cover it with varnish afterwards. Might work better for resin.

Rubs off as youre painting. Too thick out the bottle so needs thinning.Generally crap.Won't buy again.

Avoid at all costs - it's just terrible. It says its suitable straight out of the bottle but it turns in to a thick sludge blocking up your nozzle. When you thin it - it still turns into sludge

Unfortunately does not adhere to plastic models well enough to be usable. It's a little thick to go straight through an airbrush without thinning, but with or without thinner, after multiple coats, waiting 24 hours to cure, etc, the best I can achieve is a smooth coat that will rub off with very little effort, especially on edges.Unfortunately I also purchased the white, which is much more temperamental through the airbrush and similar results in terms of durability.
