So, here‘s a video w/ Cesar Guerini showing BLO in use on their fine guns. I have an Invictus clays gun that as Andrew mentioned gets dulled by sunscreen and sweat. I’ve mentioned that I use wax on both the stock and metal to help protect, but hard use takes a toll. We sometimes shoot 400+ rounds over a long weekend of sporting clays competition. Between skeet, 5-stand and SC, it’s not a problem to burn 4-5,000 rounds a year. That’s a lot of handling. I have brought the finish back to a factory sheen often using both BLO and tung - no difference between the two as far as touch up work. 6-years in and my Invictus looks nearly new. As Andrew says, oil is an easy finish to maintain. It’s just getting there that’s the pain.
All Caesar Guerini shotguns have a beautiful hand rubbed oil finish on the gun stock. With a small amount of care and feeding, your Caesar Guerini oil finish...

I realize you might not want to make stock finishing your life’s work, but you’re at a point where you can easily strip and do over. You’ve learned a lot and the process will go faster. I still think you have residual old finish that’s giving you grief. Maybe use the TruOil system the next time.
Anyway, best of luck and adios.
