You can easily repair and repaint the boat yourself. Before you start, you should decide how much money you want to put into the job. Quality marine paints are expensive ($80 to $240 per gallon). Many workboats on the East coast are painted using quality exterior house paint. It works, but you will need to repaint every year.
– If you want, the exterior “patches” can be removed and you could repair it properly for a nicer appearence
– Boat painting with the newest marine paints is really easy to do. There are a lot of choices. With today’s paints, one can get near professional results with a paint roller and a natural hair brush. This is known as the “roll and tip” method of painting. Interlux Perfection is a 2 part linear polyurethane designed for the do it yourself painter. It is solvent based (need some ventilation!) and results in a very nice finish. System Three (www.systemthree.com) has a water based 2-part linear polyurethane that is also very easy to work with. The System Three paints have a semi-gloss finish unless you apply their clear top-coat.
– The paint job is only as good as the prep work. The hull needs to be thoroughly cleaned with a solvent to remove any old wax residue. You can fix any imperfections with a “fairing” product (you can buy or mix yourself). Prime the hull with one or more coats of primer from the manufacturer of the paint you selected. Apply the top-coat.
– Rhino lining has some pluses; hides imperfections, water proof, and non-skid. The big negative is the weight. It is heavy. Too heavy in my opinion for a small boat.
The website for the makers of West System epoxy (www.westsystem.com) and System Three epoxy/paint (www.systemthree) have a lot of useful information. The Interlux website has a boat painting guide (www.interlux.com).
Good luck with your project!
