Instaling Futures boxes

Do you need to buy the video, or can someone explain the general procedure to me here, or could I just figure it out myself.

Figure it out as in, rout it out, then fill with some glass fibers, pour in resin, then stick in teh box. Then put some tape over the hole and hotcoat the board would be the way I would do it.

If not, can someone correct me before I screw it up?

Gotta set toe-in and cant, so tape the fin into the box, preventing resin seepage. Then masking tape the schmang to the rails to hold it while resin sets.
