If you are used to working with raw fiberglass then you should know what to expect. Easy instructions come in the box.
What to expect from fiberglass vs ABS Plastic. There are several advantages to fiberglass vs ABS. The parts made from marine fiberglass are generally just as flexible, lighter and stronger. The tensile strength is stronger than ABS, but it is not resistant to crushing. In the event of damage and the part is broken in two pieces the fiberglass can be easily repaired with items found at Walmart. ABS is not easy to repair and some EPOXIES that claim to stick to plastic do not. Fiberglass resin or Bondohair repair are usually stronger than the original parts. That is why racers use fiberglass race bodies.
What to expect. All of these fiberglass parts are made from marine grade layered mesh and are left unfinished in raw gel coat. The parts are removed from the mold and trimmed using grind wheels and sand wheels. Any imperfections, scratches, stickers or decals from the original part the mold was made from, will transfer to each part made. These are easily sanded away with 300 grit sand paper. All defects in the gel coat are easy to remedy and are easily fixed. It is part of the process of dealing with fiberglass. But the ultimate fit and finish will depend on the amount of prep. Things fiberglass finishes could have. Some just need a light sanding and primer. This doesn’t mean you part will have any of the issues below.
Tool marks (easily fixed with light sanding on edges)
Pin holes (easily fixed with glazing putty or filler primer)
Spider Cracks (easily fixed with filler primer)
Sticker impressions (just sand them away with 300 grit)
Surface scratches (easily fixed with glazing putty or filler primer)
Gel Coat color swirls or uneven finish (just paint over with primer)
