RE: Zymol - the estate glazes are actually very nice, of course afaik the lowest cost one is ~$800. They have a line in the $200-$500's too that is very good also. Personally I think aside from the fact that for waxes they have very good durability, you're paying for diminishing returns. With proper preparation, even the lowliest of waxes (like $20 Nattys Blue) can look 95% as good as a much more expensive wax.
Question: does being the most expensive always make a product, or service, the best?
