I just sprayed a FF tube and scope mount with Aluma-hyde II Coyote to match my Magpul furniture tonight. The color is pretty close to the Magpul FDE, but a little too shiny on metal parts if you ask me. I waited until I needed some other things to order a can. There's ALWAYS something I need from them, so it didn't take long... LOL You can also hold off until they run a free shipping or similar promo deal. I do agree though, for the incredibly slow shipping, the costs from Brownells are crazy. They're service is great and I've never had a botched order from them, but it takes FOREVER to get to NJ (probably UPS's fault more than Brownells').
I'd send you the remains, but I think I want to spray a few more parts before I ditch it.
On a side note, if you know anyone with a dealer or LEO account with Brownells, the can is a few bucks cheaper. It's not a ton, but enough to maybe ease the pain of paying for the shipping.
