I would love to hear what others do for that. I can see both ideas would work. I also like to see people doing those kinds of modifications where they can be undone to restore to original. They make metal tape that could work, but you want something that can't possibly fall into the rocker assembly and cause damage. If you are a welder, you could put a piece of tin over the hole on the inside, then weld it shut. If you are careful, it would be easily reversible. I hope others chime in!
