Avoiding Fuel Drool
2: Addressing flaking bottom paint, keeping fenders clean
During a recent haul-out
I noticed a patch of flaking antifouling paint on the otherwise clean
bottom of my boat. What could have caused this, and what can I do to fix
it? T.P., via e-mail
First remove all flaking paint. I suggest using a flexible plastic paint scraper instead of a metal one to make sure you don’t scratch or gouge the fiberglass. A few criss-crossing strokes over the area should remove most of it. Next sand the patch with 80-grit sandpaper to get any remaining flakes, making sure you go about two inches beyond the perimeter of the affected area. Then wipe down the area with a clean rag and paint thinner to remove any sanding residue. To determine if there’s any contaminant present, pour a bucket of water over the area. If it beads instead of sheeting, you need to sand some more. Once the surface is clean and dry, apply two coats of bottom paint.
I’ve got some
rather stubborn stains on several of my fenders. I was thinking of using
acetone to get them off. Is this a good solution? B.W., via e-mail
You’re better off using a product designed specifically for this purpose. I’ve had good results with products such as Star brite’s fender cleaner, a good-quality hand-held scrub brush, and some arm power. Once you’ve got the fenders clean, keep them that way with a quick cleaning at the first sign of staining.
