Jesse, he does. In the '90s, Goodall was using the "standard" Nitrocellulose. Now, that is what most luthiers used and still use (especially most high end, single person operations). It has its problems, checking after fairly long aging, or severe temp fluctuations, but it is sonically transparent. James, with the new series, switched to a polyurethane formulation that, although it requires lots of care (and is seriously dangerous to sprayers), is actually faster to apply and cure than nitro. It is also nearly impervious to chemical, temp or aging problems. There is some question as to its sonic properties - there is lots of debate, pro and con.
The other alternatives - French polish, water base formulations and a polyamide shellac that Paul McGill and Kim Walker both use - are fairly rare. Paul and Kim have a major secret in their finishing and nobody else does it to my knowledge. That is *so* clearly the best: impervious, sonically transparent and beautiful, that it is a shame more luthiers don't know how to do it or care to know. Of course, "small" shop and factory producers will never use it because it is so time consuming and exacting, especially in the polishing phase.
