I'm new in here, jumping back into the hobby after 27 years- my how things have changed! I picked up some MM Acryl, having used the original MM enamels years ago, and understand Acryl is ready for airbrushing right from the bottle. For various reasons, I wanted to apply some by brush into some tight places and found it to be way too thin to brush without 2 to 3 coats, and air bubbles form in spite of hell. Any way to "thicken" it slightly? Also, what is a good primer for this stuff? I'm rebuilding a 30-year-old 1/32 AFV with the remnants of Testors and Humbrol enamels, as well as some Polly-S acrylics. Thanks!
