I'm in CA...none at any of the local Lowe's or HD. Maybe it's a California thing. I really need a good sealer like Black Jack but can't find anyone who's tried any other brand/type.
I came here to ask the same question. I found Black Jack at Amazon, True Value and Ace Hardware. I'd have to order it and I'm too impatient to wait. Does anyone have ideas for Black Jack substitutes?
