If you have lubed properly this should be minimal.For firearms that will be used at constant temperatures below 10 F we recommend you use a very light coat of a very thin lubricant like Break Free CLP or FP-10.Ultima Lube II Grease MSDS; Specifications for Wilson Combat Ultima-Lube II Grease: Manufacturer: Wilson Combat Container Volume: 2 oz Package Contents: Wilson Combat Ultima-Lube II Grease Wilson Combat 579-2: Ultima-Lube II Grease 2 oz.
