Over the years I cut my front dash many time for many different depth finders. Now I want to fill in the hole, my thought was to cut a fiberglass sheet for the hole and epoxy it in then put a few layers of glass mat over the top and smooth it out. It would then be ready for a new round of depth finders. Where would I find some fiberglass sheet material approx 1/8” to 1/4” thick to fill the hole? It is only about 12” x 12”.
I thought about grabbing some mat and making my own but certainly someone sells it at a reasonable price.
