I saw a guy on the net who did his enfield in matte black engine paint. He prepped it and sprayed it with a few coats and threw it in the oven at 350 degree's for an hour.
The finish was amazing, looked just like a parkarized coating.
Personally, this is what I'm going to do with my .58 right now, I'm just stripping the reciever and barrel right now. It won't be as tough as parkerization but it should last a while.
Anyone object to engine paint and baking it for an hour?
The results I saw were great.
