I had a similar problem with a CZ - only I used Solvol Autosol to bed-in the parts. The safety catch was the worst part - notchy and noisy - but after coating the bolt and the safety cam with Solvol, and then working the action for about 20 minutes (I needed to reapply the paste twice more) the whole thing loosened up and quickly became silky smooth.
After stripping, cleaning and reassembling - followed by a light application of gun oil, it felt like a totally different rifle, the safety becoming completely silent and thumb-flickable and the cocking action was soooo smooooth.
Well worth a try!

Either method above will sort the inital 'roughness' of the action. I've found that using the car engine oil treatment STP as the re-build lube gives a better feel and will last longer being designed to 'stick' to metals as opposed to mineral based oils. (BTW STP is a very good case resizing lube, has taken over from my standard Imperial wax)
