I'm not usually late to the party...
I do indeed use Blackrock-I used Pecard for many years but now find Blackrock easier to use.It leaves less residue/buildup than Pecard,takes only minutes to apply, wipe off & brush & leaves my holsters looking very nice indeed. Thanks for the compliment, I have managed to find some good holsters.
