JB Bore Bright

It won't hurt. It is finer grit and is really excellent when used to mirror polish shotgun bores. The results look good, if that helps.

I use it only on new barrels to remove burrs etc. I dont use it to remove fouling, lead fouling is best removed with Outers Lead Out but patching will work in air guns most of the time.

I used the JB Bore Ceaner first time about last month, after perfectly cleaning the liners this thing was black after some 30-40 patches, I got a bit scared the Cleaner removes material. Run a next maybe 10 patches with JB Bore Bright and still were coming out black.
Coming from manufacturing background my understanding is these pastes remove material, not a considerable amount but still. Wondering if you use on a same bore let say 20x along the lifespan how much are these changing the inner geometry?

NO WORRIES!
What you are seeing is the same result as using any metal polish, the black is the remnants of the oxidization layer, sub micron layer of metal already oxidized.

This is normal and expected, just use a bore cleaner to remove any extra polish/haze from the bore.

I use the regular JB bore paste. When I'm working on a new or unfamiliar gun it's a given to scrub them clean. I've had JB paste straighten out a few guns over the years.
I seriously doubt the bore bright would hurt anything. Use it if it makes you feel better.

Is JB bore bright a polish or a cleaner? Or both? Never used it, so I am curious...

Both products, Bore Compound and Bore Bright, will serve both functions, clean and polish. However any barrel of a fair to good initial state that has been prepped with them will usually never need to be cleaned with anything other than tight cotton patches dampened with your favorite cleaner. Prepped properly using a ball-bearing rod and felts (or brass jag + cotton patches) to conform to the bore and follow the rifling to scrub everything, especially the inside corners of the rifling.

Thanks trig! Recently, I cleaned my Fortitude several times and used a brass brush, WD40 soaked swabs, dry swabs, etc, etc, etc... I think I got it pretty clean, and would have liked to "polish" the barrel, but I didn't have anything to do it with. So, I just went back to shooting and the cleaning alone made a wonderful difference! It did take some seasoning, but now the .177 Hades are shooting sub MOA at 30-35 yards and close to that at 40+ yards. I don't know that it would be any better with polishing, but I am fairly sure, I would not need to clean the barrel again nearly as soon if I had polished it when it was really clean or new. (smile)

I need to try the JSB/FX 10.34 domes again because I haven't tried them since the serious cleaning of the barrel. If the Hades are sub MOA at 30, maybe the JSB/FX 10.34 domes will be hole in hole? (grin) Or not... ?

p.s.

I may need to call you about the DAR. Having never opened it up, I have a few questions before I do the water test for the leak. I'll text or PM you first...

Thanks again! (smile)
