Yeah, after Johnson's stopped making it, the hoarding kicked in. I used MinWax paste wax for years. Frankly there are better waxes out there, some of which have less pungent solvents so the smell is not nearly as annoying or at least dissipates more quickly. The best ones usually have some carnauba wax. Not sure that I would use the Turtle wax without looking to see if it has other ingredients you might not want around your woodworking.
