Scratched Fiberglass Shower Inserts

Fiberglass Oxidation Kit

• Any fiberglass surface, including that of scratched shower inserts, can be difficult to repair without the proper tools. Before making any attempt at repair work, it’s a good idea to obtain the necessary equipment. Kits known as fiberglass oxidation kits are made for the express purpose of repairing the surface of scratched fiberglass. These kits contain special coating materials as well as pads and buffers used to rub the scratches out of the surface.

Buffing

• Though the coating supplied with fiberglass oxidation kits is necessary to fill in the scratches in a fiberglass shower insert, the coating doesn’t do the majority of the work. Instead, the person applying coating has to do most of the scratch removal by hand. After applying the coating per the manufacturer’s instructions, use the supplied pads to rub the fiberglass surface in quick, circular motions, buffing the coating to blend it into the fiberglass surface. Once the scratch is no longer visible, apply the sealer to waterproof the scratch.

Small Touch-Ups

• If the scratched area on a fiberglass shower insert is no more than a nick, you may be able to skip the intensive process of buffing the fiberglass surface. In instances of very small scratches, an appliance touch-up kit or some epoxy paint may suffice. To perform the repair, apply the coating supplied with the appliance touch-up kit or the epoxy paint to the surface scratch in the fiberglass with a disposable applicator. Once the paint dries, the scratch should no longer be visible.

Holes

• Though it is possible to repair a fiberglass shower insert that has a hole all the way through it from one side to the other, it is not advisable. Repair work should be done only on scratched fiberglass shower inserts that still have their original structure. Fiberglass shower inserts that have holes through them all the way to the wall should be removed from the shower and replaced with new panels.
