Tamiya mini acrylic X-35 is a water-soluble semi gloss acrylic coating product that was developed by Tamiya. X-35 can be applied with an airbrush or brush and for thinning the thinner X-20A is recomended. 

For the shiniest result, sand and buff before applying multiple coats of X-35, letting the piece dry completely between coats. Two coats are enough for many applications, but no rule exists. Each bottle of the Tamiya mini Acrylic Paint Series contains 10ml.
