Gregor, Yes to all your questions, but motoric is not a word I would use. It really can't be motorized - I have tried. But the rubbing is circular. The Konig special french polish may not dry any faster than the traditional. That depends a bit on the dilution of shellac though and the solvent used. The application is easier and the final shine is better with no de-oiling, spriting off, or waxing. I doubt that there is much added to the "Special " french polish except a lubricant and perhaps some slight variation in the solvent, though I don't know this and have not noticed a significant difference in odor. I am sure it is a trade secret as well.

Sounds great. If I got you right, you do the same motoric movements like with the classical French Polish, but the K?nig stuff dries quicker, needs no extra oil and no special finishing to remove oil. I am just wondering why they don?t sell it in Germany. Perhaps there are some ingredients that are prohibited in the European Union? That topic made me more than curious. Hm, I think I will ask K?nig and post the answer in a few days here.
