Repair A Scratched Bike Frame
Bikes don’t typically stink, but that doesn’t mean they don’t deserve some TLC for stains and blemishes. If your bike sports some battle wounds from dropped chains, crashes or poor handling, the concern is more than just cosmetic. Moisture from weather, sweat and storage environments can reach the frame through paint scratches, compromising the integrity of the frame.
Though bike stores sometimes carry touch-up paint, Roger Levy of Freewheelers Bicycle Store & Repair Center in Rochester, NY suggests nail polish to fix chipped paint and scratches. It’s cheap, widely available, and comes in a variety of colors, making it easy to find a close match.
To repair scratches, thoroughly clean and dry the surface to be coated, and inspect the scratch to make sure the frame underneath isn’t damaged. Paint lightly with nail polish, allow to dry, and repeat. Top with clear nail polish to seal. Inspect and touch up as needed; Levy suggests doing this every time the bike is cleaned.
