We are all about producing the finest reproductions of the frosted duco finish found on vintage National guitars. Frosted duco was a popular novelty finish in the 1930s. It is lacquer containing a crystalline material that creates a frost-like pattern in the dry paint. Because of the nature of how crystals grow, no two results are ever alike (very cool and also very frustrating at times) and as a result, each guitar unique. National used the frosted duco finish from 1931 to around 1937. Here at B•FanaticGuitarworks, we have worked tirelessly to replicate the finish used by National and as a result, frosted duco is now available again on new guitars manufactured by National Resophonic, as their Dueco Model. It is also available for restoration of your old National that has lost its original finish... So here's B•FanaticGuitarwork's story: At B•FanaticGuitarworks you can find, restored guitars, a source for restoration for that trashed but cool National or Dobro you own, and new guitars..
