Report Wash that tank Help in Armor Posted November 7, 2010 Hi Mark, Does the lacquer work well with both Testors and Humbrol? How do you thin Mr. Color, i feel that these are the hardest to work with. Pappy :) I use Mr Color leveling thinner for mr color paints as it has a leveler built in, pricey though. You can use laquer thinners but people have had problems with stringing. Laquer thinners will work with almost any oil based enamels and some say it'll work well with Tamiya acrylics but I prefer Isopropol alcohol with those. Just be aware that laquer thinners evaporate rapidly so adjust your pressure and shorten the distance between the model and the air brush, practice on a piece of scrap before committing to a model as you can't undo errors with laquer as it really etches itself into the surface of the plastic. Of course that's why we use it, more robust finnish.
