Does anyone know where I can buy the materials to properly repair a cracked plastic shower pan? All I've been able to find are either videos showing how to do it, or links to people to hire to do it, but no resources for the DIYer. I want to do it right, not just an automotive Bondo job. I've seen clips on either fiberglass layers sanded and finished with an epoxy paint or applying a sheet fitted to cover the whole bottom, adhered and blended at the edges. Both look good, but I can't find where to buy either. The manufacturer doesn't offer anything and I don't want to replace the unit since that involves tearing out and patching tile on the walls which could just cause a new problem!
