I have and still call bullshit on this. Nick gave absolutely no substantiation on to why Lexol would be bad, and it was just a passing remark. Also, DFWII is an advocate, from what I remember searching this exhaustively in the past, and dude seems highly knowledgeable. I use Lexol on all my shell without issue. Some people also are against wax on shell, or advise sparingly. I use that, too. Maybe I'm just coo-coo. I also sno-sealed shell, and there's not really any reason to do that, lol. Maybe some detriment will show itself over time, but I have shell going on a year now that is a-OK. I recommend people experiment and draw their own conclusions.
