When marking storm panels, should they be marked every 24 inches, or can a panel only be marked once?
This depends on how the panel is manufactured. Some manufacturers produce panels at fixed lengths and distribute them to retailers. The retailers in turn sell them to homeowners or installers who cut the panels to fit a given opening. Other manufacturers cut the panels for a given job as they roll out of their corrugating machine. The requirement being brought forth is that each panel installed at a sight shall bear the complete stamp of the manufacturer.
