No problems at all for coating and most our rifles get coated. I'm not sure if the acetone soak gets it or the gas out burns it off but never noticed a problem. My AO isn't contaminated because I have never had a fisheye. I'm pretty certain even ordinary rubbing alcohol would wipe most of it right off. If you are not coating the gun then no need to remove it. Like any wax it gives good protection from water.
