Buckmark is uber. Sorry about the damage.
A lot of people have a negative opinion of WK40, and mostly, rightly so. However, IMO it's good for what it is.
I've hosed rifles that were totally saturated by precip and were starting to freckle with rust.
Of course, once the H2O was displaced I douched them with brake cleaner to clean the WD off and get them dried.
All that aside, the Buckmark is uber.
