Putting a "bevel" edge on the plywood will make getting the glass to stick without bubbles a lot easier around the edges.

I hinged mine to make access easy to the tank and fittings.

Bradford did you hinge it on the v21? If so I'd like to see/hear how you did it.

Its a boat, no matter how well you seal it its gonna get water or at least condensation in it. My original tank had at least a dozen holes in it some fist sized due to water corroding the aluminum.

Hinged it just like the fish box, all hinges for all my hatches are on the port side. The tank is not foamed in, its 5200ed on treated 2x4s 5200ed to the bilge. You can rinse the salt off the tank and all drains to the bilge. No foam lets the tank breathe and sweat which its doing anyway, and allows for rinsing it off, the hinged lid allows for easy inspection plus eliminates having the pie plate inspection ports with all their screws rotting out your new hatch lid. Did this way back in 03 or 04 before I found this place and has worked great with no issues. Others will have different opinions much like etec vs yamaha, chevy vs ford, reagan vs mondale.

Wish my tech retarded *** could figure out the pics, not bragging, but y'all would love my V.

Hear are a few photos of my recoring,of my 86 v20 fuel tank panel, I used 3/4 in. Marine plywood, smooth edges, and used 5200 to attach to panel. Then made peanut butter with poly resin and talcum, to smooth out the edges. I used 1.5 oz matt,,followed by a layer of 1078. First time working with fiberglass. Next the live bait panel.
