Pettit SC-21 Fresh Water Speed Coating

Pettit SC-21 Fresh Water Speed Coating is a super-slick, ultra-thin bottom paint ideal for boats that race in fresh water. The slickness-enhancing agents PTFE, molybdenum disulfide, and bronze powder combine to reduce drag and increase racing speed.

This advanced coating is easy to apply, dries fast, and requires no sanding between coats - so you can finish faster and start racing sooner. Ultra-thin film finish means there's no paint build-up to sand down before launch next year.

Each order includes 1 quart of SC-21 paint and 6.7 oz. of SC-21 bronze powder additive. Available in Bronze and Blue colors.
