7.) Stretch t-shirt material over the frame and use a hot glue gun to keep it tight, 8.) Resin the t-shirt and let it dry hard. Then add fiberglass, though it may be possible to use fleece instead of t-shirt and skip the fiberglass(?). Replace MDF deck, 9.)Sand, stain. Use contact cement to cover console with vinyl. Use a thin layer of foam underneath to smoothen out the vinyl.
Problems and issues: Use thick enough MDF so it can support the radio. Note the cupholders were on an angle so you need a way to make them straight-up vertical. Cut the vinyl so at least one inch extends down into the console. Cut holes to let in wires from the dash and in the bottom to let out wires to the amp in the trunk. Be mindful of the heater vents, don't cover them all up. Because the plastic I laid down had wrinkles in it, the bottom of the console is rough so it sticks pretty tight on the carpet, no glueing required.
4.) Trim with cutoff wheel, add framing for supporting the deck with a glue gun, 5.) Veneer MDF deck, set/glue gun it on the frame, then draw and jigsaw 3/8 or 1-2 inch all around. You will remove the inside pieces, leaving the edge. 6.) Deck edge is screwed in place. Additional framing, to support the deck when put back in, is added. You should sand or plane the jigsawed edges to make the opening wide enough for the vinyl covering to easily fit through.
1.) Lay plastic on the floor and up under the dash, 2.) make a chickenwire frame for under the dash, 3.) first layer of glass goes on the floor and up and over the chickenwire. As it dries, use a board (not shown here) with one end anchored against the seat to keep the unit pressed all the way back.
