I saw the DIY kits a few days ago. I'm building a new dedicated .22 and was looking for something new, finish wise, so I ordered a kit yesterday.
One meter of film is actually quite a bit. It's 18 or 19 inches wide and just over 6 feet long. If I don't mess up, I think I'll have enough for a couple of rifles.
I found one place that will sell film for $10/square meter but it's a 5 meter minimum. Another place on Ebay sells it for $50 for a piece 35.5"x15'. Unfortunately, the activator is $100+ a gallon. I wish I knew what they're using to activate it. You could probably find it much cheaper.
I ordered the Predator Brown Deception. I really wanted multicam, but the places that advertise it are finishers and don't sell supplies.
Everything except the finish kit should be here for next weekend. Hopefully in a few weeks I'll post a pic.
