Lucas Gun Oil is a special blend of oil and petroleum-extracted additives. It is very economical with many uses. You can use it to waterproof and rust proof, or if rusting has already taken place, Lucas Gun Oil cuts through rust. It?s an excellent polishing compound for stainless steel and it resists fingerprints and acid contamination from touch by human hands. Lucas Gun Oil was originally developed to maintain machine guns. It resists burning out or blowing out many times longer than conventional gun oils. Lucas Gun Oil can be applied heavily for rust proofing during long term storage or applied lightly for immediate use. Lucas Gun Oil is an absolute must for the serious competition shooter. Use it to lube the inside of your gun barrel for easy removal of powder and filings. It?s excellent for compound bows and fishing reels.
