During the 13 years I owned my Bayshore custom flats boat I re-did the teak 3 times. After taping and brushing on multiple coats of Bristol finish in a single day before letting it dry for several days, I starting wet sanding with 400 grit before graduating to 600, 800, 1000 and 1,200. By hand. Toe rail, helm pod and platform toe rails. After that it was hours and hours of polishing using 3M Finessee It compound. By hand. Yes boats are fun. I also ate a lot of fried chicken and drank a ton of beers in the process.Please make a point of doing a bit of research before getting started... once you’re sure about what you intend to accomplish all I ever needed was wet or dry sandpaper, a hard rubber sanding block and a small water bucket. For my purposes I started at 220 grit paper, then 400, and ended with 600 grit.
Hope this helps
Aren’t boats fun?
