I had some Frog Lube paste given to me and I used it on a couple 1911's and it seemed about like any other quality grease except it smelled better than all the rest. Clean up was easy but grease clean up on a 1911 is normally easy.
I still have a lot left but I went back to Mobil 1 red synthetic, as that is what I like best.
Frog Lube will not clean out copper or lead buildup. What I use for copper is Boretec CU+2 or Boretec Eliminator, both will take out copper as fast as anything on the market that I know of.
I also didn't find Frog Lube to reduce bore copper fouling - to me it's just another excellent firearm paste that has the best smell on the market IMHO.
