People are always asking on forums about undercoating and varnishing and I always mention my preferences, now I will have a spot I can link to..huzzah!!!
For priming, and in the case of my cheaper paint jobs undercoating I use these sprays, .I purchase them from Bunnings or Magnet Mart or anywhere I come across them. They are around $11AUD each. .These are superior to other purely hobby branded spray cans , being much more robust in their finish and only half the price. The Primer ,I have been told is an acrylic lacquer, and dries quite hard, goes on easily and covers well. From that point I either spray them with the Matte black or undercoat in Tamiya flat brown through the airbrush.Always allow 24 hours for the Primer to dry. It dries dead flat..if you have shaken it up well. The black, on the other hand being only Matte has an annoying sheen.
When the miniature is finish I then coat it with the above, with a thick big brush..and allow to dry. If you are going to use Testors dullcote then I find this to be a crucial process.this being a Matte, not a flat, dries with a bit of an annoying sheen..but..
then comes the final varnishing ..I am just beginning to use Dullcote again..I used it all the time when I painted in oils and enamels.. but I found Acrylics a bit delicate . It is usually safe if you have sealed your mini with the Jo Sonja's Matte..if not it can eat you acrylics right off to the metal.
But my favourite is seen in the last picture .Gunze H20 flat clear..if you have let the Matte varnish dry completely, and conditions are perfect, or near perfect, then I run it through the airbrush, mixed well in my paint shaker for about 2 minutes, with about 1:5 ratio of Windex window cleaner/Varnish and spray away .
People don't take seriously the paint shaker..bad luck for them I say. An absolute must in my opinion. especially using tear dropper acrylics. I routinely shake all my new dropper bottles before first use., and it is a boon in "recovering" paint that has dehydrated to some extent..a small amount of Window cleaner and a five minute shake and you can usually bring dieing GW paint back to complete a useful life.
