Ahh
I wish to you greatest patience possible if you intend to use tube acrylics.
When I started my ABing, I did that mistake you're going to make now. I bought Daeler&Rowney System3 and Marabu. So you see those were not crappy products.
To say shortly, I had terrible tip dry, build up of the paint
inside the nozzle, when AB started to throw paint only when pressing the trigger not even pulling it back. "Normal" work started from 0,3mm nozle, 0,2mm was a nightmare.
I've diluted them with water, mixture of water and window cleaner, mixture of water and pure alcohol. Water was distilled.
I've made experiment. Poured some water into some paint in one cup and pure alcohol into another. Left to seat them overnight and haven't mixed. Water dissolved the paint and alcohol has not. So you can make your conclusion what work and how with acrylics.
To save your nerves and your cash, I'd advise even not to think about tube acrylics. Just buy normal AB paint and enjoy painting, but not destroy your nerve system.
People here call good AB paint E-tac, Wicked, Createx Illustration etc. You'd better chose among these. Haven't used any of them, so can't say exactly. Personally, from this forum members descriptions, I'd try E-tac first.
I use urethanes and can say they're great, no issues with them. But work with them requires charcoal respirator and ventilated studio.
