Home Forums Hunting & Shooting Ask The Gunwriters Dyna Bore Coat

I've let barrels sit a week. All thats happening is the carrier is evaporating
and then you have to heat treat it to get it to stick. Timeline doesn't matter much. I do it as quick as I can but not worried about it.

Not totally clean? Might have to retreat, IE scrub with JB paste etc.... and retreat. I've had to do it a few times on a stubborn gun. Nothing negative other than it just didn't work quite as well.

too little won't coat. Too much will run out.

So it has a consistency of basically water? And one bottle will do 4/5 rifles?

Once I DBC a barrel, I never use a brush again, just soak it with Eliminator or Patch Out. A patch is the most aggressive cleaning device I use.

Mostly I get them bore scope clean with one or two such treatments. Seems they’re easier and easier to clean.

Several years ago when the company had a female support rep. I was able to call her and ask her several questions.

First question was does a 22 rimfire round give enough heat to cure the Dyna Bore Coat.
Her answer was yes.

Second question was shelf life of the product.
She said one year. I disagree with this but of course her aim is to sell the stuff. As Mule Deer has stated, as long as it is liquid, and not hardened, it works fine. Keep the bottlecap on tight and store it in the fridg. I have an almost empty bottle in the fridg that is about 4 years old, just a drop left and every time I open it to check it it is still in liquid form.

Third question was what was the longest allowable time that you can wait from installing the Dyna Bore Coat in the barrel till you have to shoot it to cure it.
Her answer was indefinitely, didn't matter. She said if the barrel is clean and you coated it properly with the DBC , the glue hardens/sets and you have a protective coating in your barrel. At any time after that you can fire it to cure it.

Yes it does have the consistency of water once you take it out of the fridg and let it get to room temperature. Make sure you shake it well before using.

If you are careful, set things up so as you install the DBC through the muzzle and have the bottle RIGHT underneath it to catch the drips, you can get way more than 4/5 rifles treated with one bottle.
The other trick is to try to use the same patch for rifles of the same caliber and do them at the same time. For example, if you have 6 .22 rimfires, have them all cleaned/degreased, then DBC them all with the same patch on your rod. You will find you have used hardly any DBC at all in the process because it is so thin. More DBC is wasted in the patch that is discarded(and the drips that don't fall back into the bottle) after use than is used in the rifle barrel.

I treated 29 rifles and one pistol using just one bottle of DBC in this manner with nary a problem.

Thank you wink man, great instructions.

I put the barreled action in a padded vice, chamber up, bore down.

I attach a shotgun hull to the end of the barrel with tape.

Any excess product drops into the hull and I recharge my mop from there, so there is no waste.

wink,
Those are some impressive photos - both for clarity and cleaning results.

Thanks, and taken by a cheap $50 Teslong flexible borescope no less.
