fellipe- Welcome to Autopia!
I'm far from being the resident expert on rinseless washes, but I see a few (potential?) problems with using a synthetic chamois for this:
-Mine never got 100% of the water off, maybe close, but they always left a *tiny* bit behind (which I either got off with something else or just let evaporate) and I wouldn't want to risk that with ONR
-Related to that, IMO the drying with ONR/etc. involves a bit of "buffing" as well as "drying" and a damp Absorber/etc. wouldn't, IMO, be well-suited to that
-If there's any residual dirt (that'll get taken care of during the drying), the lack of nap makes the synthethetic chamois risky with regard to marring
-The synthetic chamois' pores might "load up" with the polymers/etc. in the ONR, rendering it less effective
I don't even like using a WWMF for such drying, preferring a plush-style (MF) drying towel.
