I know there are some old threads on this, but after some digging around I found a few distributors and figured I would post the info for anyone looking for the stuff.
Dow distributes directly to Hubbard Hall their phone number is 203-756-5521 They have distributers across the country. There are two in the Southern California area.
1.) Loyalty 949-654-9510 (Los Angeles)
2.) Golden West Lubricants 626-442-3009 (South El Monty and Pomona)
Golden West was a bit cheaper @ $147.00 for 5 Gal.
There are two other companies Dow directly distributes to that I did not call, they are:
1.) Ashland 800-531-7106
2.) Brenntag 800-852-0372
