though instead of buying your material from autozone which most likely will be Bondo brand i suggest you go to fiberglasssite.com to get your fiberglass. pick up 1.0oz to 1.5oz mat. it's easier to work with curved areas and such.
then purchase some resin at Uscompsite.com look for one called b-440 Premium polyester resin. its a great resin to work with. has very long work time and easy to mix with the given hardener.
then just go to home depot and pick up paint brushes and tape and all other materials you need.
