| Howdy Barry, Yes, the Alcad "polished aluminum" paint requires the use of a high gloss black "base coat". Both the "base" and "color" coats are Laquers and must be applied via airbrush. Once the base is dry (or in my case with this model, reasonably dry lol) you "mist" on the "color" finish with your airbrush....very little at a time. It is truely amazing at the finishes you can achieve with these paints. They are however, abit on the expensive side. The polished aluminum and gloss black base bottles cost me the better part of $20 (US). have a good day, Greg |
