Ok brothers I need some suggestions on how to fix this livewell. I bought a Taho-Rig Livewell at a garage sell for 20 bucks. The thing is to get it to fit under the deck I built I had to cut a piece off each side of it. I now need to refill the holes. What do yall suggest? I was thinking about fiberglassing it but not sure how never have before. Here is some pics of what it looks like. It is made of plastic.
