Very good question. One that I asked myself more than once as I was hanging up side down in the box squeezing air out of the glass layup
and picking epoxy out of my hair.
Like Nick said, I wanted the finish to withstand all of the impact of all the things I'm going to drop on it. I also wanted to ensure the joints in the marine
ply were strong enough to hold what will be probably be over a hundred pounds of beer
. And food
, we put food in it too.
Another cautionary tale I heard was about a couple (friends of friends) who had some work done on their boat. The guy doing the work shut the battery
switch off and then didn't turn it back on. The owners didn't get back to the boat for a week or so. When they did, they discovered the huge bag of shrimp they kept in the freezer
was completely melted. Somehow the shrimp juice had seeped through a crack in the freezer
box and had permeated the insulation
. Now they have a boat interior that will smell of rotten shrimp until they rip out the fridge.
I wanted to be 100% sure that no water
or shrimp juice would ever have a way of getting into the marine
ply or the insulation
behind it. I will sell this boat before I ever re-build that fridge again.
