Gunsmithing Barrel Refinishing

[smschulz]

I want to refinish my Rem 700 5R Milspec (SS) barrel.
Do I need to bead blast it or any other prep (other than degrease/clean) or can I just apply directly on.
I plan on using heat cured Cerakote.
also
Any advice on keeping the sheen down (flat)?
I am having a hard time getting a flat sheen with GunKote.
I am going to use CeraKote over GunKote as it appears it is more durable but am hoping for a flatter finish as well.

Degrease and blast with 120gr alum. oxide. You need a good base for the coating to adhear to. Check NIC's site for instructions on prep. and application.

sms with respect to keeping the gunkote sheen down it is very important to apply very thin coat. I have found that if I put it on to thick it get a bit shiny.Gunkote comes in different sheen levels make sure you have flat. I would +1 the above comments re prep for coating

No question prep is everything.
On the barrels I GK'd they were already bead blasted new SS barrels.
I did K-Phos treat them prior to finishing and did heat prior to the first application.
I did not re-heat on subsequent coats to the same degree (used heatgun on add'l coats).
Only the OD barrel came out flat enough for some reason the rest ~ way too much sheen.
Could the K-Phis have anything to do with it?
I did a phosphated BCG and it was flatter than the barrels (used flat GK).
Should I reheat between coats in oven to 150 degrees?

I suggest you read the directions that come with the Cerakote coating. Following the directions for me has always lead to a very flat finish.

I have never used Cerakote before (also read don't have any nor seen any <span style="font-style: italic">directions</span>)
"Following directions" is always good advice but not very specific.
