I needed to smooth out some rough patches on the bottom paint last year before some touch ups. I used my plain old palm sander on the ablative paint. A mess. I will have to do the same thing this year, and I want to get a new sander that has a dust control system. Any recommendations? Also, how do you deal with the toxic residue that gets all over the unit? Do you use the sander only for bottom paint, or do you take the thing apart to clean it so it can be used for other, less toxic projects?
