Is there a Canadian source for Blanco? A friend of mine wants to coat a Jeep top. I'm not sure if that would be authentic but I'm trying to help him out anyway. The only source I've been able to find is in England and only in 100mL bottles. He'll probably change his mind once he calculates the cost. (He says he used to get it in 5 gallon pails in European surplus stores and I imagine it was a lot cheaper that way.) Since the cost of actual Blanco is likely to be prohibitive, which of the commonly available canvas dressings would be a suitable substitute?
