Nearly every DIY maintenance project has a low-impact, eco-friendly option, but be careful—some “greener” substitutes can set your project back by days, and bring unexpected costs.

1. Several “green” chemical strippers designed to peel away bottom paint proved effective in our testing (see “Bottom Paint Strippers, PS October 2006).
2. We added 20 percent Kleen Strip Green Paint Thinner to Minwax High Gloss Polyurethane. Within a few hours a thick layer of sludge appeared in the bottom. It became stiff overnight. This thinner may be okay for cleanup, but for application, you should stick to the maker’s suggested thinner, and confirm the chemistry.
3. A safe solvent wipe is essential prior to applying sail repair tape to areas that have been lubricated by silicone. Otherwise, the tape adheres poorly.
4. Water-based bottom paints make DIY painting far more palatable.
5. A port is cleaned for rebedding. A solvent can be so strong that it removes the original protective paint or coating. Always test first.
