Re: bought dinged up board
You will need to determine if your board is polyester, or epoxy this will determine the kind of repair kit you will need to buy. You will need to get some resin with hardener, fiberglass cloth, Q-cell (resin additive to make a filler), sandpaper, masking tape, and some mixing cups. The cost varies and sometimes you can buy a large size repair kit with most everything needed, including directions. Since you are new to this I would go the kit route. Remember even if you mess up you can always sand it down and try again. Try to read the instructions really well and it can save you a lot of time. You will probably spend between $15-$25. Good Luck!
