[jetblue319]

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.
