Took a deep swallow and bought 2 gallons type of asphaltum, recommended to me by Quinn J my book teacher in the States. Cost was $232 CAD for everything, including $37 USD for shipping ($31 USD for 1 can, $37 for 2, so I bought 2). There will also be the brokerage charges etc.
Had to give this stuff a try even thou it is $116 CAD plus per can. It might be more archival than the acrylic paints I have been using so far. All the clear glass wet platers love this asphaltum stuff. Hurts to buy it thou, the cost for AMBROTOS KANATA continues to climb.
