Any ideas: I need to tighten my bow eye and the bulkhead is full of spray foam. I have seen posts where people have cut a hole to get your arm through. My question is what product can I use to cover the hole when I'm done. I've seen where people used bow lights but I can't find one  big  enough that I can get my arm through. Has anyone run into this problem and what did you use. Any information would be appreciated.
