Many of the repairs need to be done to boats with Polyester/Vinylester rather than Epoxy resin. As a general rule, Epoxy can be applied over Polyester/Vinylester but Polyester/ Vinylester can't be applied over Epoxy. In order to match the colors of the existing hull, gelcoat must be used for the final finish. For best adhesion of the gelcoat finish, repairs should be completed with Polyester/Vinylester. The gelcoat is custom matched to your repair area then spray applied. It is then wetsanded to a 1000 grit and buffed out to match your existing finish. One thing to remember is that, as gelcoat ages it discolors with dirt and grime. The older the gelcoat gets, the harder it is to obtain that perfect match. Gable Enterprises must see the damaged area in order to give you a quote and inform you if a match is obtainable. Come on in or give us a call for an estimate.
Technical Information: Gelcoat is available in polyester or vinylester versions. The vinylester is superior to the polyester version. However, it is more difficult to apply. Gelcoat is used as a finish on most production boats today. It's longevity and low maintenance make it a good all-around finish for the boater. As gelcoat ages it needs to be maintained more and more. The maintenance involves a buffing and waxing. This maintenance can be performed until the owner notices that the finish isn't looking as good as it used to between buff jobs. The most common reason for this is that the gelcoat is actually dying!
When gelcoat dies it loses all of its UV protective resin on the surface. Once the resin is gone, the tints/colors are left on surface. These tints absorb discoloration and dirt easily making it difficult to keep clean and shiny. If you swipe the gelcoat with your fingertip and a chalky color is apparent, then your gelcoat probably has outlived it's usable lifespan. Your gelcoat is dead! The most cost effective fix usually is a new polyurethane paint job. However, "regelcoating" of the surface can be done, but it's a costly alternative as after application, it must be wetsanded and buffed. This wet sanding and buffing is labor intensive and therefore runs the cost up.
