How much radious do I need? Could I radious the outside bottom edge, glass the bottom edge of the wall, letting the tape hang off the back edge of the wall a bit and wrap around the front, then trim the excess glass with the router after the epoxy cures?
If I found a 6oz tape would I still need the radious?
Don't use tape at all, cut your tape from cloth. Cut the strips on a bias. It will follow any contour and there will be no salvaged edge to try to bury. When cut on a bias, there won't be any frayed edges to deal with.
Tape is difficult to hide with epoxy. Cloth will bury easily. I use thin glass for tape, one wider one with a narrower one on top of that, this make's it much easier to blend without showing.
You will still need a radius. Fiberglass doesn't like sharp edges.
