Model Master Acryl Thinning for Airbrushing.
OK, before I get flamed, I did a search on this very topic on these forums, went to the Testor's website, searched Armorama and ARC forums and I get different answers from everywhere.
Do MM Acryl paints need to be thinned prior to airbrushing? I just tried to shoot some RLM 78 on a 1/72 Bf-109E4 Trop using my "normal Tamiya" 1:1 ratio, even used the Testor's proprietary thinner, and it was like shooting water out of my AB (an Iwata HP-CS) and I ended up with clumpy crap in the cup. This was a brand new bottle that I mixed with the little battery powered Badger paint mixer.
I sprayed a primer coat last night with the same AB with Tamiya XF-19 and X-20a and had no issues.
These very forums said :
2007 No they don't need thinning (referenced a post that has been deleted)
2008 Yes, they should be thinned
2009 They are able to be airbrushed straight out of the bottle.
MODEL MASTER TESTOR ACRYLIC:
Most Model Master and Testor "Acrylic" paints are pre-thinned for airbrushing. Thin paint by adding thinner drop by drop, until your consistency has been achieved.
Air pressure should be approximately 18-20 PSI.
Acrylics will dry to the touch in minutes; they require 24 hours for a full cure.
I really do try to not be an idiot, but I swear, this is driving me bonkers. Should I just add the paint into my mixing jar, take a little up in an eyedropper against the glass, and see if it has that "2% milk" look to it, and go from there?
Any help would be appreciated... my little 109 has a spot on my shelf just waiting for it, and I don't want it to be homeless much longer.
