after you get done, put the fiber glass cloth on, the use the fiber glass, then after you've coated it a few times, sand it, then use a filler (such as bondo) to fill in holes, gaps, or to even it out, then sand that.
Woah, woah, calm down tiger. ;-)
Remember, the fiber glass clothe is what to lay down to put your fiber glass on. You can't just use the cloth. :mrgreen:
Def. use an exacto knife or a large pair of scissor is you don't have craft scissors or an exactor knife.
