No, HL doesn't have an extensive selection of military colors in spray cans. That is a disappointment. That's a lot of the reason why I started switching to the Vallejo paints. I was already enjoying the use of Daler Rowney artist's acrylics and Tamiya acrylics as well, so it was an easy switch. I also started with a knock off no name chinese siphon type AB on canned air. Getting a Neo with a compact compressor as an early present made my world open up like crazy.
So take advantage of a sale at HL and grab an Iwata as soon as you can. They come around once in a while and that's when the best time to take advantage of the prices.
