Hobby Poxy and Klass Kote are great products. I used them exclusively on my racing boats. On prop planes I now use Stits and on my jets I use auto paint like PPG or Transtar. A word of caution. Once the epoxy catalyst has been opened, use it all, soon. I found that it yellows quite a bit with age and a nice bright white Part A mixed with aged Part B will mix up as an off white.
