Body work is an art, and is why it is usually the most expensive repair done to a car. It is the easiest thing to cob job, and make look ok but it wont last. Honestly if you screw up one step above your repair will last a year tops. Everything must be done perfect for a repair to last years and for the untrained eye to not know a repair was ever done.
If your going to tackel it, have the right tools, and a heated clean garage. Ask specific questions and I will help you the best I can. Read up on autobody fourms too there are lots of guides out there.
go to the junk yard, get an old hood. smash it with a hammer and repair it. practice before you try it on something you care about.
