I was partially finished this project three years ago, once I got it in the water I just wanted to go fishing and put all projects on the boat in the can. Now I'm finally trying to continue where I left off. I want to try and bring the original luster to the existing gel coat on the hull. Under the boat it looks so shiny and pretty, but do to the 29 years with the sun the sides have lost any sign of luster. The hull is white gel coated, with a few spots that look like someone had sprayed some krylon spray paint. (Should this work: Sand with an orbital sander until I achieve a uniform coloration throughout the hull. Then wet sand to achieve smooth surface. Next buff with some form of polishing paste.(what ever yall recommend). Then hit with a good coat of wax,(whatever recommended.) There is a little cracking around the top 2 inches or so right beneath the topside, but its due to the gelcoat being sprayed over the mettalic gelcoat thats incorporated into the accent stripe on the side, just want to get most of the side of the hull looking decent. Last question how do i make sure that I don't sand two deep into the gel-coat when sanding, whats a good guideline to follow. Tell me what yall, think even though my post may sound kind of choppy. Thanks to all!!!
