I ran out of my Army Painter Quickshade varnish. The AP dipping method was inspired by the older and much cheaper Minwax dipping technique, and many wargamers think that Minwax (a floor varnish) is actually the same product as AP, but with a different price tag. I researched the question. I’m a wargamer on a shoestring.
Wargamer Pumper Jones did a test. Conclusion here.
