If your nonskid deck gelcoat
has worn through..there is an excellent remedy.
I removed the hatch
cover on my Islander 30....40 yrs old and went to Home Depot paint
department. They measured the color and made a perfect match with Behr porch and floor paint
Coating the non skid is a breeze with a small 3 inch foam roller...about $3 at Home Depot. The foam permits the roller to deposit the paint on the raised gelcoat
without touching the adjacent flat gelcoat.
Been doing this for many years...when the paint wears off, simply recoat. I have a near perfect match and am able to redo any gelcoat surface with ease.
