They can last a lot longer than that but that’s about the duration that frp has existed for boats, probably early ‘60s is when production boats started to use frp hulls. Frp is great for fuel tanks and exhaust systems - it’s superior to stainless for these applications (corrosion resistance being key factor). But yes as mentioned by sibling UV will definitely degrade
