I rinse the paper now and then in the soapy water, and the body, under the faucet. Might take some time, but it will smooth over nicely.

I always hear people say to wet sand things, but heres my question on it as i have never done it, when you wet sand does the filler loosen up or soften up at all? I tried it once after using regular modelers putty but when i got the body wet and started sanding it just started taking chunks of my filler out... Not sure if it was the filler i was using or i didnt let it cure all the way (waited 2 days) but i have had no luck with it. Any ideas as to what i may have done wrong? I have some more filling and sanding to do on my fenders and the smoother i can get them the happier ill be.
