Your boat is a major investment. Proper care is essential in preserving the exposed surfaces and the value of your vessel. Boaters need to know how the sun, salt water and other elements can take their toll on fiberglass, gel coat, metal and vinyl. Why is Detailing Important? Detailing seals and protects your gel coat and extends the life and value of your vessel. Poorly maintained hulls and topsides create a buildup of oxidation leading to cracks in the gel coat. These cracks allow moisture to get under the surface resulting in de-lamination and soft spots.
