I've tried a few things, including the use of Matte clear coat. The clear coat helped make this finish last a little longer, but finally it too started looking crappy again.
Anyways, frustrated, I stripped off all the spray paint, and re-painted one of my markers with Dupli-Color 1200 degree black engine paint. This paint has ceramic, and anyone who has used it knows it is super resistant to gas & oil once it is set. Anyways, I followed the standard steps of stripping, cleaning, and drying my marker. I painted it as directed by the spray can, and after 3 days of drying, I baked it in the oven at 300 degrees for about 2 hours. (Remember to remove all plastic parts & o-rings before baking). If the paint is not allowed enough time to air dry, baking it will make your house smell like paint fumes.
I am happy to say, the finish is a nice looking flat black color very similar looking to Tippmann's powder coating. Once finished, I put a little paintball paint in a somewhat hidden spot on the gun, and I think the ceramic paint will hold up perfectly to paintballs.
