I'm fiddin' to haul my H34 for a bottom job. (I'm doing it) and I want to grind the keel down to bare metal and fill in all the pits and smooth it out and paint it, etc. So, I guess I need a primer to put on the bare metal, a filler to smooth over and fill in the pits and then the bottom paint. Is that it? What else? What are the best products, procedures for this? I know this has been discussed before. Thanks for your help.
