This is where the finish is at now...
Ran out of Testors dullcote, so tried some flat varnish from Lifecolor. Bottle directions indicate that water can be added. If you are familiar with Tamiya's flat base, this stuff results in pretty much the same look and can easily end up looking too chalky and any pooling will likely dry white.
On my second attempt, I added a few drops of future in the airbrush cup, and also cut down the product 50% with plain tap water. It laid down good, but I think it's still too flat.
regards,
Jack
