I recently purchases a used C/L airplane and motor for $10. I knew it was finished in Formula 'U' paints. Aero Gloss' manufacturer says they no longer manufacture the 'U'. I found some color spray cans down at the local hobby shop and purchased them. I have finished planes using other dope brands but never Formula 'U'. If i'm not mistaken, Formula 'U' isn't even a dope. I could use some advice on using Formula 'U' for refinishing my model. Do they have a clear? Does it come in bottles so you can brush it on? Any advice or help would be welcome. Thanks. Dave G.
