Are you doing this by hand? Or are you using a system like 3m's Hookit where you use high speed DA sander with 1200,1500 or 2000 grit paper.
I used to wet sand, now I use the 3m system. Of course i've only done this right after painting, but I'm sure it could be used years after paint has cured. Do a search for it, way easier than hand sanding.
