Nevertheless, without a regular and proper maintenance, the moisture and saltiness inherent to this environment can reduce their service life. A dedicated cover for the whole boat is the best protection against UV degradation of gelcoat and fabric of the tube.

    SERVICE AND MAINTENANCE PLASTIC PRE SERVATION Surface quality may degrade by solar exposure, heat, salt deposits, anthropogenic pollution and vehicle exhaust gases. The gelcoat surfaces will last a long time if regularly and properly cared for. Keeping the surface clean and periodic waxing are key points in gelcoat care. In the marine environment, protection of plastic surfaces must be applied more regularly than on your car because the sun is stronger and the horizon is longer than on shore.

  • Page 93: Salt Removal

    Be sure to read the instructions before application. Preferably choose the time to work or position the boat so you can work in the shade, both to keep the surface cool and to keep from going blind. Golden Line G420 Owner’s Manual...
