Mailport February 2013 Issue

Mailport: February 2013


I just had a boatyard recommend PPG ABC3 bottom paint for my fiberglass sailboat. I never heard of it before. Perhaps it should be included in the bottom paint tests? Do you know anything about ABC3?

ABC3 is made by PPG Protective and Marine Coatings (, a global company head-quartered in Pittsburgh, Penn. PPG’s products, which include the Amercoat and Sigma lines, are generally marketed for commercial and military ships, not recreational fiberglass boats.

ABC3 is a high-performance, tin-free ablative with controlled self-polishing. One thing to keep in mind with these types of paints (epoxy ester resin mixed with a rosin), which were designed for working commercial ships, is that they tend to crack and flake when they’ve been left out of the water for long periods, like during winter storage.

We’ve never tested the ABC3 formula, however, Practical Sailor contributors Achim and Erika Ginsberg-Klemmt are carrying out an experiment on their Florida-based aluminum sloop using one of PPG Amercoat’s other paints, Dimetcote 21-5 (PS, May 2012), which the Ginsberg-Klemmts have been pleased with.

We hadn't included PPG in our panel tests since they aren’t marketed to recreational boaters, but we’ll see whether the ABC3 or other Amercoat products would be a good fit.
