I had an eclipse back in the day with a full body mold, started with the front fenders and went all the way to the rear bumper everything was molded, except the front bumper. it deff. look awesome, and really isn't all that hard to do. I also did this with my friend WRX, this is how I did it, both held up great for years.
1)strip the paint off in that area using some rough sand paper to give a little tooth to the metal
2)then use some fiberglass and resin to fill the gap between the two body panels.
3)once that is dry grind that down smooth lower then two panels to be molded.
4)I recommend using a long strand body filler or mar-glass over that, because the long strand filler will hold together much better then regular body filler.
5)grind that down smooth barely lower then body panels to be molded.
6)use a short strand body filler to fill in the small imperfections from the last step, and bingo all molded together.
make sure to throw primer on the body filler as soon as your done, as it is porous and will suck up moisture
and always do your body filler in thin coats, it sets up way better in the long run, because it allows the gases to escape while drying.
the only down fall to molding your panels together is should anything happen (get hit, hit something) god knows it happens to us all, to repair it you would have to repaint the whole truck, unless you got a good body guy that is really good at blending paint.
good luck
