Are you using there pro oil dyes or the regular dyes?
Also the eco flow stuff isnt much against water so you may end up having to switch to something that is a little more resiliant in advers conditions.
Have you tried playing with topcoat, tancoat, or similer. I like tancoat followed by a good sno seal.
Would like to add that there are alot of people with more experience with this so check to see what they do with there holsters and other items that are used in bad weather and conditions.
