    Saw in someone else's post a suggestion to use alumablack to restore finish on a Mossberg 500. I've got a 500a that needs it bad, so I'm thinking about it. Anyone use it, how easy, are you happy with the results?

    Alumablack is, in my experience, the most worthless fluid ever put into a little plastic bottle and sold.

    I would NOT expect to obtain any sort of satisfactory finish on a Mossberg 500a using Alumablack. No, not at all. It is Most emphatically, Beyond a doubt, Without question.....useless stuff.

    Yeah, its pretty much worthless.
    It says on the back of the bottle that depending on the alloy the color will be between black and gray. So I went back into the machine shop and grabbed every type of aluminum I could find, about six (6061, 5052, 7075, mic-6, 2024, and 1100 IIRC) and not one of them got more than a gunmetal color to them, one even started to smoke and pit! Even the ones that were "finished" could be returned to normal with a little elbow grease and a paper towel.

    It would be best to choose another finish,

    Then you've never has one of those little cheap tequila samples!

    And alumnablack does suck. The black rubs right off.

    At least I'm not all alone. I bought a bottle for my Benelli when i bought it. It was in like new condition, with the exception of some deep scratches on the inside of the receiver. I'm still not sure what the previous owner did, but he was clearly not happy with his choice.

    Anyways I noticed that the warning say that it may remove old anodizing, which it certainly does. I tried it on a small spot on my M1S90, and wiped it off before it could do any more damage. It didn't work at all. I've also tried it on different pieces of aluminum, and it doesn't really work.

    OK, so what to use? I've got a Remington model 31 16 ga. that's been refinished -it's a beautiful gun! But the trigger assembly is aluminum, and the finish is flaking off pretty bad. I don't want to 1/2 ass it with spray paint, so what other options are there?
    Powdercoat? If so, how expensive is something like that, and who's going to want to do 1 little part without charging more than the gun's worth?
    Thx

    Don't rule out paints/coatings right away; there are quite a few that yield excellent DIY results
    I've had good success an alloy parts with Wheeler Cerama-Coat and Dupli-Color High heat 1200 degrees ceramic paint. The Wheeler product goes about $20 a can and Dupli-color about $6; both are bake on.
    Here's a P229 done with Cerama-Coat (I sprayed this on to achieve a orange peel effect):

    This Single Six grip frame is done with the Dupli-Color:

    You might also look at Gun Kote, Aluma-Hyde II, DuraCoat, Norrell Moly-Resin, or Cerakote.

    Regards,
    Greg
