Well, that was fun.
Back on topic, this is one to file away: always use the correct solvents for the materials you're working with.
It's always safer to stay within one family of brands for color, clear, thinner/reducer, retarder, etc., since these products are made to work together. When it's not possible, a little research goes a long way. Read labeling and MSDS for every chemical you use, and keep those MSDS on file for future reference. Important stuff.
