I need to put a couple of additional holes in the floor of my UHaul
to run wires to allow the TV to charge the camper battery
. The floor is in excellent shape and I suspect it is because it was originally carefully laminated and the plywood inside has been protected from the elements.
So my question is: How do you reseal the edges of the hole to maintain the integrity of the lamination? Do you drill the hole oversize and insert fiberglass mesh and resin to seal the edge? Or maybe create a little mold and pour pure resin around a tube through the floor? What kind of a drill would cause the least amount of damage to the edges?
Thanks in advance for your thoughts.
