I used this to seal the finish gelcoat when repairing chips I had on the underside and stern edges of my bass boat's hull after encountering sunken boulders while fishing. While some of the silica powder is clumpy in the container, as some reviewers point out, it doesn't matter since you'll be mixing it with gelcoat resin anyway. I couldn't have done a patch repair without it and would definitely buy it again.
