I don't see any advantage to that. To start using FL, you need to completely strip all of the petroleum base product off of it with isopropyl alcohol anyway. I used FL on my FS MP9, MP9c and Nano from day 1. Couldn't be any happier. It is SO much quicker and easier to clean after a range session when using FL....all you really gotta do is wipe down well with a microfiber cloth. Read up on their website and you tube reviews...you won't be disappointed.
