AK 3GEN disaster

[Dr P]

Purchased AK 3GEN colors for WWII German armor.
After priming the model, I attempted to base coat is with the dunkelgreb paint.
Used their High Compatibility Thinner to thin before spraying.
Now I have a tank with a mess for a finish.
It looks like sand was sprayed all over the tank.
I guess I assumed that the High Compatibility refereed to all of their paint line.
What did I miss?

It's not compatible with the non solvent base acrylics .
I assume the 3rd Gen is not a solvent acrylic --- I don't have any but I do have some of the AK acrylic and it definitely turns to snot when mixed with the High Compatibility Thinner .

The alcohols in that thinner set off polymerization with the acrylic resin in the paint .

Can you recommend a commercial thinner? Thanks for the response.

I like the Vallejo airbrush thinner .
It's mostly water but with a small amount of propylene glycol as a retarder and ammonia as a surfactant .
Golden also makes a similar product .
AK should have a solvent free airbrush thinner for it --- I'm not a fan of their website .

IDK why they named that stuff " hi compatibility " . It ain't .
the first bottle I got of that stuff , forever ago , I read the label and said , " oh , this looks like some hot azz chit ... probably not good for brush painting ,, but let's see ,.. "

it contains a glycol ether , butoxyethanol .
That used to be listed on the label but the newer bottles no longer tell you anything .
neither does their website .

AK Interactive High Compatibility Thinner contains a mixture of 1-methoxy-2-propanol and monopropylene glycol methyl ether (also known as glycol ether) to create a versatile solvent for various paint types.

I enjoyed your tag line. I was told. years ago that when you got a PhD you learned so much that you knew everything about nothing. It was true.

It was true

Considering the inverse, ' knowing nothing about everything' , not so bad...

That's probably because (scientific) knowledge these days is extremely specialised (and getting ever more so), as there's so much of it that nobody can be a true polymath anymore. You're not simply a physicist these days, you're a laser interferometry astrophysicist — and chances are that you get questions on very basic physics basically wrong because they're so far outside of your specialist area that you know barely more about it that a secondary-school student.

The academic sequence, bachelor to doctorate: First you get your BS. Then you Make Some more. Then you Pile it Higher and Deeper.
