Cleaning the gelcoat surface of your boat is an important part of routine boat maintenance. The gelcoat layer helps protect the boat from the elements, and using a Matt Chem Marine #1 gelcoat cleaner product is by far your best choice.
Remove the dried hull wax, using small circular motions with a clean lint-free rag. Change the rag often, to reduce the amount of wax residue left of the hull when using the gelcoat cleaner.
Pour a small amount of a green hull gelcoat cleaner in a plastic bucket. Pour water down one inside wall of the bucket -- to minimize suds -- until the bucket is 1/2 to 3/4 full. Scrub the wet hull with a scrub brush and the hull gelcoat cleaner solution, starting from the highest forward point, and working your way to the back--transom.
Fiberglass is a lightweight, strong composite that works well for constructing RV, car bodies and boat hulls. The material made up of very fine fibers of glass. Fiberglass is resistant to heat and fire and is used to make various products, such as building insulation and boat hulls.
Empty the bucket of soapy water when finished cleaning the tub. Refill the bucket with hot water. Rinse the sponge free of the soapy water.
Deck washers can save themselves lots of work by first pre-soaking the deck. Before you begin the gelcoat cleaner scrubbing process, hose your deck down and allow the water to sit on the surface for several minutes. As the water sits, it will loosen any residue or debris that rests upon the deck surface and will make it much easier for you to remove.
The easiest way to remove dirt and grime from your deck is with a deck brush and gelcoat cleaner. Purchase a coarse-bristled brush specifically designed to scrub decks. The bristles on this brush will easily scrub into the groves of nonskid surfaces, making deck washing easier to accomplish and stripping away dirt with less hassle and effort.
Modern sailboat manufacturers lay fiberglass cloth with polyester resin to create the hull, deck and framing members of the boat.
Inspect the area once more. If the stain is still present, dampen the disposable paintbrush, and then use the dampened brush to apply a thin coat of polishing compound to the stained Gel Coat. Use the 7-inch polisher to spread the polish and get the stain out.
Let the product sit on the gelcoat. These products generally take 15 to 30 minutes to neutralize the rust stains. The products react with the rust stains and, if used according to the manufacturer's instructions, will not cause harm to or affect the gel coat in any way.
Do not use gelcoat cleaner products such as Goo Gone or acetone on gelcoat surface.
Removing tape from a fiberglass surface leaves the sticky adhesive residue clinging tightly to the gel-coat covering. "To give the fiberglass a smooth, shiny outward appearance, a material called gel coat is applied to the outer surface," according to Technology-USA. Abrasives or potent chemical cleaners either scratch or soften the protective layer. When these areas are damaged, they will have to either be fixed or replaced. The removal of tape adhesive residue takes only a few minutes when using the proper tools and techniques. Protect the gel-coat facade by using a safe and gentle product.
