My long supply of solvent is coming to an end. I have never tried ballistol. A few questions: 1. Is it a good enough lubricant by itself? 2. Is it safe for plastic? (Was not a concern 100 years ago) 3. Does the smell linger in the room or on your clothing for a long time? 4. Why do you think it is not very popular for smokeless powder guns? I will appreciate the time you take to respond. M.
