What is the best ratio for Testors Primer & paint thinner for airbrushing? I put 1 part Testors Primer and 1 part thinner, but I’ve noticed that my primer doesn’t seem to be drying quickly and still has a “sticky” feel to even after 48 hours.
FYI, I’m airbrushing with an Iwata Eclipse CS. I would appreciate any help or direction. Thanks.
Depending on how thin the primer is I would start at 2:1 (2 parts paint to 1 part thinner) as that is my normal ratio for most colors.
Is that thinner compatible with that primer? It sounds odd to still be tacky even after 48 hours.
I concur with Mike. You didn’t use enamel primer and acylic thinner or vice-versa? - You would know straight away if you used the incorrect thinner as the two would refuse to mix and would separate in sticky lumps.
I used Testors Airbrush Thinner (1789). I think you are right though. I should be using a higher ratio.
I 'm kicking myself now because I looked on the back of the bottle’s directions and although it does say “For enamel paint only”; however, it instructs that for flat colors, the suggested ratio is 3 parts paint to 1 part thinner.
For me to use 1:1, I have way too much thinner in my mix and no wonder why it’s not drying. I’m lucky I practiced on scrap plastic and not my real model.
That’s always the wisest way to do it! [tup]
