Re: Paint Remover for anti-fouling paint

We stripped about 25 years of old ablative paint off our Grampian 34 a few years ago. We started with a soy-based stripper, which did soften most of the layers. It worked well, but b/c we were working outside, we had to cover it with plastic wrap for 8-10 hours while it was "cooking." This was a challenge, but fairly easily doable.

After the allotted time we pealed off the plastic to reveal a soft gunky slop which easily scrapped off. This we scrapped onto plastic sheets. What was left was a thin layer (streaks really) of bottom paint which we then sanded down with an orbital sander.

The stripper worked OK, but in the end I reverted to simply using a big paint scrapper, and then finishing with the orbital sander. The stripper probably required less elbow-grease, but in the end I'm not sure if it's any easier than scrapper and sanding.

Why go fast, when you can go slow.
