Ok I am working on my sub box for my trunk. and right now I got the whole box buttoned up and ready to go but I noticed when I cut the middle brace I cut it a bit short and there is about a 1/16th of a gap on the bottom. I am not sure if caulking is going to seal it good or not. So I was thinking of just glassing that center brace where it meets the bottom of my sub box. Would I be good it I just brushed some epoxy fiberglass resin in the crack or do I also need to lay down some fiberglass chop matt as well?
