      • So, to begin, we need a nice clean working area. My place is small so I used my patio set (not the best idea though, as my wife flipped when she found out I was using toxic chemicals where we occasionally eat, just beware.)

      • Things you will need:

      • Surfboard with dings

      • Cleaning tools: wax comb, rag, and Gloves!!!

      • Resin, Q-Cell Filler, Hardener, Fiberglass Cloth

      • Mixing cup, stirring stick,Transparency

      • Sand paper: 1 rough grit and 1 fine grit

      • Starbucks (optional)

      • Next, you need to identify the dinged areas and figure out which method you prefer to use. I used cloth repair on the bigger ones (and the rail ones) and then the sun cure on the small ones (because I have heard it works well enough on small stuff).

      • Now we need to clean the dinged area of all the wax and fiberglass flakes.

      • Grab your comb and scrape any wax from around the area to be repaired.

      • Sand down, approximately 1/4", till you have a nice smooth surface.

      • Cut a small groove (in the direction of the ding) to give the repair mixture somewhere to seep into.

      • Now we come to the mixing process.

      • First figure how much resin you are going to need to adequately cover the cloth piece with a little to spare to pre-dab the dinged area.

      • Add Filler, it helps to make the solution less watery and more workable

      • Then add the hardener; you only need a little and it really depends on the temp. Your box should say what is appropriate for your particular weather.

      • Mixing Process (Continued)

      • Put the fiberglass cloth that you cut into the mixture.

      • Stir the cloth in slowly to cover the cloth with mixture without causing air bubbles.

      • Application Process:

      • Pre-dab the area with some of the solution, if there is a chunk of the fiberglass gone, use the solution generously to fill void.

      • Spread the soaked fiberglass cloth over the dinged area and smooth it out with your fingers.

      • Use the transparency to spread the cloth evenly, working out any noticeable bubbles.

      • Application Process (Continued)

      • Hold the transparency in place (be aware that it will not stay put).

      • Use tape (scotch, masking, painters) to secure the edges and make sure the transparency is held down tight

      • Curing and Finishup:

      • Let the mixture cure.

      • It should take, depending on your weather, about 1 hour or so to dry completely.

      • Don't remove the transparency until dry.

      • Once dry, remove the transparency and use a fine sand paper to even out any new bumps from the new fiberglass surface.

      • Then, voila! your board should be back to working order. Get out there and this time try to be more careful on the trip back to the car. ;)

You forgot step 0 - choose a well-ventilated area (like the outdoors) before opening those aromatic chemical bottles.
