Home Forums Hunting & Shooting Ask The Gunwriters DYNA-TEK Bore Coat instructions revised

I believe the stuff they used to send in the kit was denatured alcohol. That’s what I substitute now and haven’t had issues.

Thank you both. I found the bottle and it appears to be denatured alcohol.

Yes, it is.

I think stuff like the Dyna Tek products are required by federal law to have current MSDS sheets for their products for your viewing pleasure and protection. Look up that document and you will find out what is in it.

yep found it

I am wondering ,how often bores need to be re-coated ?

I used it once on a hard-fouling 264 Win Mag. 1) Was uncertain if I was correctly following "instructions" (PS If your product requires precision to be successful, then create precise instructions); 2) no noticed reduction in fouling.

Any idea on shelf life and where it should be stored?

Supposedly 1 year shelf life. Store in a fridge or cool area.
Best you ask the company. If they respond, but that’s what I heard.

Revised the bottle and package I received had no lot # or born on date to be found. So who knows when it was made.

When I have to reapply (which isn't often) I clean the bore with a strong oil-based copper solvent, then thoroughly degrease with acetone, which works just as well as alcohol but evaporates quicker.

Mentioned on one of these threads before that the metal canisters used in the past few years preserve DBC much longer than the plastic canisters used for a while, even without refrigeration.

The choke info is gold.
Thanks.

Hey John, let’s put this sh*t to rest. Put up a contact with the company for support.
I’ve sent 5 emails & over 25 business days no response as to whether they even support the product. Sh*t S&W which I consider piss poor CS only took 5 business days to tell me that they didn’t support that anymore. Never have waited that long except when they don’t.
Give me a good contact and I will shut the hell up.

Double post for Swifty...

This is the first iteration of the instructions I received with UBC:





And this is the latest revision I received on a separate paper, before they stopped including paper instructions:

Jordan, post mortem is one of your best suits but since you decided to sh*t on me after the fact, where the f*ck were you and all the others when I asked questions back in August. I do appreciate the post mortem post info. But right now it’s helps like pissing into the wind.

Not sure what you’re talking about. Link to what I said that you took offense to? I just dug out the documents and scanned them today, to try and offer some help to those looking for detailed instructions.

IME, the few times I’ve seen DBC not work as advertised, it was because of installer error. Not saying you don’t have something else going on, that’s just been my observation and was likely my assumption when I initially read your thread.

I like how he’s mad at you because he didn’t know how to google easy to find instructions.

Tonight I bore coated 3 Bartlein barrels, 25 Krag Ackley on a Krag action, 250 Savage on an 1899 Savage action, and Rem 260 on a Rem700 action.

I put their muzzles down through the dog holes on a woodworking bench for the bore coat to dry.

Maybe I'm crazy, but I dont get to crazy procedure wise when installing DBK. Starting with a perfectly clean barrel I run a loose bore mop through the barrel several times, wipe any excess off the muzzle, let it dry for at least 24 hours or until I shoot the gun and that's about it. I am completely sold on the stuff. Especially for my varmint rifles. I have 500 rounds through my rem 700 VS 223 Rem prairie dog gun without cleaning. I shot it on paper the other day and it's still shooting great. Same story with my CZ 527 204 Ruger.

I have also gotten away from the break in a new barrel thing.

I use it in every rifle and shotgun I own. Really works well.

I read John’s first article on this stuff, years ago. I’ve never used it, and didn’t know, until seeing this thread, that it had caught on so well. Seems like I recall in John’s initial article, that the application procedure for bores over 30 caliber might be a little different. Is this true, or is my head full of cobwebs? I think I might like to try coating a few medium to large bores. Thanks
