A note to the "4200" Fan-Club.
The quickest & easiest way is seldom the best way.
Remember, if you don''t have time to do it right in the first place - where will you get the time to fix it?
If the existing holes, and the surrounding solid fibreglass are in good shape (no spauling, no hole elongation etc), overdrill the exit''g holes and epoxy, then re-drill to size. "4200" can (then) be applied as a deck sealant.
All rig fastenings should be "backed".
