Gas tank installation

[SCSeacraft]

Blue,
I used 1.5 inch strips of .5 inch starboard and ran them lengthwise down the tank to let any water flow out and to allow air to criculate around the tank. I used plenty of 5200 to completely seal the starboard to the tank and not allow any air pockets where the white rust can have a chance to attack the tank.
Hope this helped.

I read some where to use Fiber reinforced plastic. I can't imagine it maks that big of a difference. What about plexi or something cheap? A 5 foot sheep of starboard is pricey.
