After finsihing decaling, I'm preparing to airbrush my model with a matte finish using Tamiya XF-86 Flat Clear. I've never used this product before, but my understanding is that it is specifically intended for use as a final coat (and is a different product than Tamiya Flat Base X21.)
Before I begin, I am hoping to get some advice from those who have used the XF-86 Flat Clear in an airbrush, so that I can get a good flat coat with no frosting.
1) What is the best thinner to use for this product? I have Tamiya X-20A on hand, which is what I would assume would be best to use, but am not sure.
2) What thinning ratio would you suggest? Normally with Tamiya acrylics I thin at an approx. 2:1 ratio of paint to thinner, to the consistency of skim milk. But with a flat clear, should it be a bit thinner than that, say a 1:1 ratio, to avoid it going on too thick and causing frosting?
3) What PSI would you recommend? From my research, it seems approx. 10-15 PSI at a distance of 6 inches or so seems best for this sort of thing.
Thanks for your suggestions. Just want to be sure I get this right as it is the final stage of a model that has taken a long time to build! I obviously plan to do some tests first but am hoping someone can steer me in the right direction. There's always something new to learn with this hobby!
