Do-It-Yourself Fiberglass Repair on Jet Ski Hull
Here is a handy guide to help jet ski owners easily perform DIY repairs. Even the most cautious rider can easily scrape or chip the hull or may even notice stress cracks beginning to form in the high impact areas.
What are jet ski hulls made of?
Jet ski hulls are typically made of SMC or Polytec, but some of them are still made of regular fiberglass. Racing jet skis often feature a carbon-fiber hull to reduce weight.
What is SMC hull?
The hulls of most personal watercraft are made from SMC, or Sheet Molding Compound. You can identify it because the substrate is white and has glass fibers in the damaged area. Sheet Molding Compound is like a mass-manufactured form of fiberglass.
Whats the difference between gelcoat and Flowcoat?
Topcoat, also known as flowcoat is the term used for gelcoat which has had wax solution added to allow it to be used as a finish like gelcoat where it is not possible to use a fiberglass mould. All polyester gelcoats suffer from inhibited cure when in contact with the oxygen in the atmosphere.
