I have a Les Baer Premier II and have been using a Blackhawk Serpa holster. The slide has some rub marks from the holster and was thinking of having it Bear coated. When I call LB they said they don't recommend that finish if I use that particular holster because the Blackhawk will still produce the marks. How will this finish be any different? I really don't care about the esthetics of the marks but more how, if continued, they will affect the deterioration due to rust or other such contaminants.
