I absolutely love my FRP skin. Light weight, super durable. 100% salt water resistant and pretty darned inexpensive. No need to paint but it is a plane-Jane skin. Wipes clean. I don’t think that paint would even stick to it.
I didn't know it was called FRP when I bought it. The panels are held on by 2 magnets each. The knobs are also held on by magnets. I need to do a panel for the end still.
