Using paste on a fire hose strop kills the point of getting the hose strop in the first place. Assuming the hose is flax linen, you are no longer really stropping on linen. The linen is there but it's clogged with wax, oil, greasy binders, and embedded abrasive powder. All the characteristics of the flax fibers are muted or shut down, only the compound stands out. The flax linen does best when left alone, not forced to 'break in', not washed to death, and kept reasonably clean.
You don't get 'more' out of the compound by putting it on firehose. And with razors tuned up on chromium oxide, less is usually better anyway. A slight dusting on a soft cotton strop is way more than enough. If it isn't, that means honing is in order, not more aggressive stropping on compound.
Crox can be applied to almost anything and it'll still be capable of sharpening stuff, so it's not a matter of "it won't work" if you put it on substrate A, B, or C. It's more a matter of being able to realize the true potential of an investment in the shaving system.
