Gunsmithing Duracoat preping steps?

[marshjo]

Hey guys,

I am looking for duracoat preping steps. I am wanting to duracoat my barrel and action on my remington 700 sps SA. I am not sure what all I need to tape off and if I need to lightly sand or not. I am totally new to it, so any help is greatly appreciated. Also, would matte black be pretty close to the same color finish that is on a zeiss scope?
Thank you,

Justin

The best way is to bead or oxide blast, degrease with acetone, then spray. The flat black would be the closest match to your anodized scope tube. If you don't have a sandblaster available, scuff everything with a green scotch brite pad, degrease, and spray.

I think with dura coat if you are painting over a blued finish the dont recommend scuffing just good cleaning.
if you are not going to blast it first.

Clean and degrease with a non residue brake cleaner like crc.
I plug the chamber and cover the breech face with modeling clay.
Blast with 120 grit aluminum oxide at 45 to 50 psi.
Blow off all media and coat using several light even coats.
Let each coat "flash off" or dry a bit before another coat.

Can you use sand to blast for prep work or does it have to be bead blasted?

Don't beadblast for finishing, it peens the surface and doesn't promote finish adhesion. Aluminum Oxide is far superior for adhesion of the paint.

You can lightly blast the plastic parts as well.
