When in doubt use the thinner made by the paint manufacturers. Save the alcohol for cleanup.
This is good advice. Next time you get a chance, read the ingredients on Tamiya “yellow cap” thinner on the side of the bottle. There’s no drug store alcohol anywhere in there. I seldom have problems when I mix paint with proprietary thinners, it’s when I deviate that problems inevitably arise. For cleaning my AB, I buy a gallon of lacquer thinner from my local HD or Lowe’s for about $10 and it lasts me a long, long time.
