I used this to apply the general finishes water based interior poly product sold at rockler, as recommended by the salesman. ( also recommended on the can of finish). I was not all that happy with the results - I bought two of these pads. On one of them, MANY of the filaments ended up in the finish. Didn't really notice so much as I was applying the finish, but I sure did when sanding between coats! Also as I washed out the pad, I could see that about 30% of the filaments where gone.
