Cal 25: Cabin Painting

Hi All, Per Charlie H: the inside skin [Cal 25] is thin (a layer of cloth and some crappy paint that won’t sand) . I scraped the flaking paint off the cabin including v-berth. If it won't sand, what should be the next step to restore the interior? Thank for any advice and tips! Marv Gross Cal 25 Banshee Marina del Rey, CA

I prepped Nemesis' interior with a wire wheel on an 18v sander, followed by heavy sanding with 80 grit. That took care of the flaking. 2 coats of interior semi-gloss white gave me a finish I can libe with. You might want to fair and use high gloss, but Im not particular. Fred Haas 3-30 Nemesis Tacoma

Thanks, Fred. Sounds doable. Marv

To make matters worse, my Cal 20 spends her off seasons in a storage yard with no electric power nearby, so sanding or wire-brushing was not an option. So I started with paint removers. First, the gentle, safe kind. It didn't budge the stuff. Next, regular, poisonous stuff. Not much better. Finally, the most powerful version of Zip-Strip. That did the job. That also uncovered a few areas where the fiberglass wasn't resin-saturated, so I added some epoxy there. Then I painted with Pettit's Dura-White, a paint for boat interior use. It has since been re-named by Pettit. They touted it as sticking to anything without sanding, even glossy surfaces. It's also supposed to have anti-mildew properties. It's a semi-gloss finish. I had mine tinted at the hardware store from a chip of the old paint. Their computer matched the original beige color exactly. It has been durable and washable, even for the spider droppings.

This conversation came up before with similar comments made. I will warn others again. Based on my observations when I stripped my interior - If your stripper removes that "paint" it may also remove some of the resin. I doubt unsaturated cloth was found in places. I believe the cloth was desaturated by the stripper.

I examined it carefully, trying figure out whether the stripper were responsible. I concluded "no," and even if the answer were yes, the problem was so isolated (and so easily fixed) that it didn't matter. It came nowhere near creating structural issues. I concluded that Cal likely used that thick paint-like coating intentionally to cover up resin-saturation problems. Chris Campbell > >
