How to Use Bleach on Gelcoat
Gelcoat adds an eye-catching brilliant shine to boats, airplanes, tubs and showers. Technically it's a resin coating covering the fiberglass. Without it the surface would look rough and dull. Since it provides protection to the fiberglass, it's critical to upkeep the gel coat properly. Bleach is often used to eliminate mildew, but harsh chemicals and abrasive cleaning techniques should never be employed when working with this coating. Scratches lead to cracks, which can eventually compromise the entire fiberglass structure. Proper cleaning takes an hour or less and results in lasting protection and beauty.
