One jar will last you a long time. To moly coat your barrel, you need a good cleaning rod (I prefer Dewey 1-piece nylon coated rods) and lots of patches for your caliber. You need to take extra special care not to get any of the moly on the bolt, chamber, reciever internals, or the action. A chamber plug would be a good investment. If you can't afford a chamber plug, just be extra cautious.
Apply a thick coating of the moly paste to the bore with a saturated patch twice running the patch through the barrel 4-5 times.
Clean any excess moly paste off of the muzzle and chamber immediately.
Run a clean patch through the barrel three times.
Then another clean patch through the barrel 30-40 times and again with a clean patch 30-40 times to burnish the moly.
Your bore should now be uniformly moly coated and will be black and shiny.
Did I mention to make sure your bore is clean first? Make sure to run several dry patches through the bore first to remove any oil. After you moly coat, throw all of your bore brushes away. Don't use them on moly coated barrels!
