ive had nothing but positive experience with those products... the "realistic rust" however is very orange out of the jar, has to be mixed a bit with some of the darker. ive tried many techniques, this product thinned with alcohol is by far the easiest and it doesn't come off in your hands when dry. I haven't had the need to seal it in with dullcote either. for trucks , they have an aged rust that is spot on. simply wash the whole thing with brush and you are pretty much done. and the larger jars help out with g scale since you use more. I use acrylics for the more detailed oils stains / rust pitting etcCool. I've heard about the Dr. Ben's stuff. Have you used it in conjunction with acrylic paint washes?
