FRP fuel tank?

I am working on a composite tank project for my Stryker, I want it to be low profile and fit perfectly in the space between the motor, pfp, and waterbox...I think the kart tanks look terrible and out of place in a nice jetski. My plan is to build it in 2 halves using vynil ester resin and fiberglass with a visual layer of carbon, imbed alum blocks to drill and tap afterwards where the fuel full and pickups will go. I found a fuel tank coating product called kreem to use on the 2 halves before they get bonded together

Coating both halves prior to bonding will almost guarantee it fails, the fuel will find the seam and get under the coating.

Just get a 550 tank

The 550 tank works in so many setups, somebody should sell a new tank in this size/shape. Blocking off the fill neck gets over 4 gallons but unscrewing the pickup assembly to fill is a bit of a PITA.
