Black 2.0 & Black 4.0 durability

hey yall. tested a leather patch. used 70% alcohol wipes to while it down before using the angelus deglazer. set down two coats of the 2.0 then one of the 4.0. used a head gun between layers to make sure it was dry. i’m really surprised it’s so flexible! i genuinely expected it to break apart. i have yet to seal it. going to put it on some air forces to test the strength that way.
