KC's Aging Paste is a dark creme you brush on to achieve a old dirty weathered look to your craftsman structures. We have also found it to be a great medium to simulate wood on hydrocal or labstone parts by first priming the part with Rust-Oleum Khaki Camo spray paint. You simply Brush on and wait a few minutes and wipe off with a cotton rag. A little trial and error on some scrap is recommended to get the hang of your required look. Until now we have only sold this at shows after demonstrating it. But now by request we will be now offering it on the website. Keep an eye on our Facebook page we will soon be putting up some demo videos of Aging Paste at work.
