If you use f/G cloth, sand the area well with 80G sand paper. Cut 3-pieces of cloth about 4" long, each overlapping the one before (set aside). Apply a thin coat of resin on the sanded surface. Put a piece of F/G cloth (the smallest one) on the sanded surface (enough to overlap the edge of the guard about 1/4"). Use a cheap paint brush to apply just enough polyester resin to wet the cloth. Lay piece #2 on top of the 1st and wet it out with that brush. Then lay the 3rd over the second. Each layer should overlap the previous buy about 1/2". Just tap the tip of the brush on the third piece to soak up some of the resin from previous layers, then just add enough resin to wet the last layer and and brush down any arrant strands. The key is to not use too much resin. Just enough to wet the cloth. The strength of the F/G is in the cloth, NOT the resin. Too much resin will weaken the patch.
Wait about 15 minutes for the layup to start to set and the resin is still a little tacky. Take a razor blade and trim off the F/G that is overhanging the edge.
Always do F/G work in temps between 65* and 80* F. Never below 60*. The warmer the temps, the shorter the dry time and the less time you have to work. 75* is ideal.
You will only need about 3oz of resin. No need for anything fancy. Bondo makes a small size of repair resin. Be sure to follow the instructions for mixing catalyst. Each type of resin is unique.
