Ok @Yukonrookie I might have gave the antique the wrong name.
This is what i use, but most of the time I hear it referred to as antique gel, so maybe I been misinformed.
This is natural veg-tan with a resolene resist coat, then let dried & the antique gel/paste applied & let set 30minutes.
Then i reapply resolene to remove most of the antique gel/paste.
This leaves all the low spots darker/antique looking.
