rhuff...I just ran over to my auto supply house and picked up a qt of Klean-Strip. I put a thick coat of it all over the frame...too early to see results...instructions say it could take a few hours and may need repeating...fingers crossed.
Ken D...just saw your email...MEK is next if the above doesn't get it.
Once again, thanks to all for the suggestions. Will update with any new results. Steve

Give a try at a overnight soak in regular old gasoline....it worked for me on some unknown finish on a old Hi-Power

Sunday morning update...no luck so far. I soaked the barrel/rcvr overnite in gasoline...didn't touch the black stuff. I had also left the Super Strip on the frame overnite...no change this morning. So, it looks like either propane torch to try to burn it off or head to the bead blaster. It may take a few days to get new info, but I'll post when available. I do check the links you all suggest...thanks. Steve

Sorry to hear that my stuff didn't work for you. That is definitely some "bugger tough stuff"!!

Tuesday update...the last couple of days have been very frustrating...haven't seen any progress...we were close to breaking out the propane torch, but GT and I got together again and tried one more shot at using a solvent.

RHUFF, this Bud's for you! GT had picked up an aerosol can of KLEAN-STRIP (I had been using it from a qt can)...there was a very visual difference in the reaction when sprayed on. Clearly good things started to happen. It wasn't going to be a quick stripping, but we now feel that with time and multiple applications, it will come clean. I was concerned about the different result of the can vs. the spray, so I called the manufacturer to see if there was any difference between the two...answer was, NO...they are the same. So, I took the rest of the qt can and dumped it in a metal pan and have submerged the "offending" parts in it and will let the soak with occasional stirring for 24 hrs. I also bought another spray can as a backup for after the soaking. I'm thinking it may well take multiple cans. The only thing I can think of for the different reactions is perhaps a shelf life problem. Ours came from two different stores. The guy at KLEAN-STRIP confirmed that the active ingredient is Methylene Chloride.
All other suggestions are duly noted and on the back burner for now.
I'm hoping for "clean" pictures within a week...I'll share. Steve

addendum to above...It is also requiring vigorous wire brush action at about 1 hr intervals. I have both stainless and brass brushes...both types are small with fairly soft bristles. Toward the end we may go to 0000 and Acetone for the final prep before sending off for re-bluing. Steve
