I'm not too big on "special purpose" stuff. Chemicals either work for a certain use or they don't - they don't care if its on a gun or something else.
With that in mind, for lubes, I use mostly 3-in-1 Oil out of the tool area. For choke tubes and recently on slide rails I've starting using a few dabs of Wal-mart brand Super-Tech lithium grease. None of my guns have ever complained that they weren't getting Hoppes or Rem-Oil
.
For solvents I actually use Hoppe's No 9, but I'll likely be making a big batch of Ed's Red soon and using that.
