blasting a barrel

[anthonyinva]

I have a high polished stainless barrel form a bench gun and now making it a varmint hunting barrel and dont want the shine. I have a sand blaster, could I use it to get a dull finish by using glass beads. What about a paint that you dont have to bake on if I want a camo or black finish?

thanks,
anthony

Bead blast will give you a gray satin textured finish any flat enamal pait will readily adhear to it. You might wipe it down with acetone before painting to remove any oils.

If you were going to blast it for a coating I would use Aluminum Oxide; if you were going to use the blast job as your finished appearance I would use glass beads. As far as paint that doesn't need baking. The link above is for air dry Cerakote. I've been using it and it seems to do very well. We have only been using it for a couple of months but it seems to be very durable. Brian Brown.

There are several different grades of glass bead available, 50/80 & 80/100 are two that come to mind, what works best for a satin finish?

Just blast it with what you have and see if you like the results. If you dont, then ask, IMO

That was a big help. I already don't like what I'm getting thats why I asked.
I picked up some 80 grit glass beads at Rural King Supply I plan on trying some later this week, I'll post on how it works.

I didnt know you had tried them. Wasnt busting your chops. I know that alum oxide works well for paint prep and sometimes I have customers who want that finish only on ss barrels. I have read that glass is too soft of a material to etch very deep. Post some pics and maybe I will learn a new finish to offer : )

I don't paint barrels but an associate of mine that does will not bead blast a barrel before Duracoating. He says that it actually gives the metal a polish and makes the coating less likely to adhere. He sandblasts, parkerizes and then Duracoats. Just information FWIW

Refer to Rusystud post, either will work but sand will be duller. If the paint isn't sticking, it's preparation.

Both Durakote and Cerakote specifically recommend NOT using glass beads to prep. They recommend Al Oxide. I have had best luck using just that. The paint fills in quite well and they are not at all rough when done. I have used Durakote and the Moly stuff that Brownells sells. Neither are as durable as the bake on Cerakote but quite serviceable.

Glass beads are for removing gaskets and giving a satin sheen to a stainless part that will NOT be coated. It is better than a high polish but far short of the results achieved with the proper grit of abrasive material.

I camo'ed a stainless Omega muzzleloader. Didn't do anything to the barrel which was relatively smooth. After a thorough degreasing the first coat was with aviation zinc chromate, left it set a week. Then did the rest with Krylon flat camo paint and some stencils for a leafy look. Did one color and some stencils at a tiime, letting it sit for a week before applying the next color, as directed for a chip proof finish. Took a month but six years of HEAVY usage and it's still looks good with very minimum chipping. If I ever need to go back to the original, thinner will do the job.

Beads give a nice satin finish if you want flat the use the heaviest roughest sand or blasting material you can. I went to a machine shop where they blasted valve stems using some type carbide grit. Made sure bore & receiver were taped & covered extremely well. Some think its ugly but for me it's practical and when I painted it with flat Rustoleum it looks even flatter. Works for me.

Ok guys I have been trying glass beads on a break I installed on a barrel that was already bead blasted. Mine turned out darker and rougher than theirs. I want to match a Remington factory finish on their ss actions. What air pressure are you using? Are you using a pressure pot or siphon sysem. I also have a floor plate that is scratched up and want to paint it, anybody know want will match the factory color they put on the ss models?

Thanks,
Anthony

glass beads has silicone in it, and that will prevent anything from sticking to it, with out a good clean up..
Cheapest way out is Rustoleum Professional flat black.
Looks good and will last for quite a while...

Another option is the SS wire wheel.......
