Went to my local Rockler today to get a quart of Watco. Seems everything was taken from the shelves last month due to AQMD (Air Quality Management District) restrictions.
OSH paid for a variance to sell their remaining stock, so I was able to get a couple quarts there. Also stocked up on Oil Varathane as it was taken off Home Depot's shelf last week.
Way things are going, I'll have to get friendly again with my brother in Spokane.
