When is the best time to know if a paddle needs repasted. Mine is about 4 months old and the feel on the .5 side is starting to feel different then the side I have hardly used, the 3.0. It is starting to feel rogher than usual. also, when I repaste the .5 side, what type of paste should I use and can I simplyu paste over the old surface or does it need cleaning pumice etc. This was a pre pasted TM 4 side paddle pasted in 3, 1 and .5 microns.

I have grown to love this thing. It keeps my razors going on a daily basis quite well.
