I bought a black composite Lotus BJX from Mike Galt in Tampa and stored it upside down in my backyard in Woodstock, NY. My young son thought it would be fun to jump off the back deck of the house onto that hull, undoubtedly having Royalex experiences in mind.
CRACK!
Well, I put a strip of black tape on that crack and it's stayed that way, with replacements every five years or so, for the past 37 years.
