I have a like new 15 lbs bottle that needs the leaky bottle valve changed to my new one...I don't want to scratch the heck out of it, so does anyone have a trick for changing the valve out?

Problem is...I can't hold the bottle tight enough to get the old valve to break loose. I tried holding it while someone else used the wrench on the valve...no go. And the vottle wants to spin in it's mount when I tried it that way.

Also...do I need to put liquid teflon on the threads when I install the new one?

I can honestly say I have never tried to change one. The only time I have ever had a valve removed was for hydro testing to re-certify the bottle. So with that said, you may wish to contact your local fire extinguisher repair shop to see what they would do for removal and sealant. I know for $25 they re-certify the bottle, so it should be easy for them to change the valve.

Thats a good idea...I considered a welding supply....but I figured they may scratch it all up since they don't usually need to go easy on their bottles finishes.

put a bottle nut on the valve and hit it a few times with a rubber mallet,it will break right loose,you don't even have to clamp anything on the bottle itself

Hold the bottle with a strap wrench.

I got it!! Thanks for the ideas....I wrapped it with my fender cover and had my wife (she didn't want to swing the hammer...lol) sit indian style holding it and I hit the wrench with a rubber deadblow....it still wasn't easy, but it did work.

I saw it sealed with a rubber o-ring so I just installed the new one....but after I was done I saw the old one had a little teflon paste on it (I didn't use any on the new valve)....does it need it?

No, O ring will be fine.
