For painting plastic, thou seeketh this…. It actually slightly etches itself into the surface of plastic. I’ve used it on many a project with awesome results and long term durability.Normally I don't bother to paint magazines and if color is important I just buy them that way. However, I'm branching into 300 BO and want to make darned sure those mags are easily and visibly different than those used for 5.56. My interest in 300 BO is subsonic, so I went with the special PMAGS with followers and a few other tweaks to make them work better with the heavier bullets used in subsonic loads. They do have a slightly different texture and feel by design, but it isn't enough to be fool proof and they only come in black.
I've decided the safest way to proceed to to paint them to a color ONLY used for those mags. In this case it will be a green or a green/brown combo.
Reading various threads I've seen several ways to do this, but I want to make sure that what I use will stand up to use and not have to be reapplied every year or so. While I treat my firearms with respect they are tools and get used. Magazines might wind up getting repeatedly dropped during changes when training, for example.
I'd like to know what you have used and how well does it hold up? Also, is there a technique I have missed that could meet my needs?
- C-Series (air dry) Cerakote: It can be applied using equipment I already have. It's more expensive, but worth it to me if the scratch resistance and adhesion to the polymer plastic is effective
- Brownell's Alumahyde II: Specialized paint for firearms and has a reputation for durability.
- Duracoat: Also a great reputation and a bit on the spendy side. I do have the necessary equipment for the two part product and of course there is the pressurized "ready to go" version.
- Kryon, Rustoleum, etc..: Inexpensive and available everywhere. Not sure if it will hold up well.
- Wheel paint: Pretty tough as it must be for it's intended application. Not sure if it's available in matt finishes.
