So the product I wanted to use would be either King star board or Coosa board. A sheet of 1/2 star board was 240 dollars 3 years ago when I last purchased it. I imagine a 3/4 in sheet would be well over 300 dollars apiece at this time. Coosa board is another good alternative, but a 3/4 in sheet is 420 dollars. Im at 118 a sheet puls my epoxy cost, so around 182 a sheet currently. The reality is I keep a boat about 2-3 years before I want something different, so it should be rock solid for the next guy.
Jeff and I spent last night rocking out on the sheet metal fencing. I decided to take a saw and remove most of the bottom channel and use some rivets to hold it in place on the lower part.

By cutting off the lower channel, it made the metal installation a breeze and no creases at all.

I left a few tabs to fold over and secure it and the rivets held tight in locations where it pulled out a bit.

We were able to do this as all one piece instead of the two originals because of this method and it came out seamless. I hammered over the lower tabs and end tabs just to hold it in place and will go around this afternoon and drill and rivet it on the bottom. I have one more to do and then I will redo the first one in this same way since I creased the metal. Wife is super happy with how its coming out and once the plastic is off you can see the subtle metal flake in it.
