I'm no body man and I don't even enjoy body work but I have done some dent removal. Don't just grab a hammer and start pounding that dent out. You can do more damage than good if you stretch the metal from blows with a hammer. There is a book out there called "Key to Metal Bumping" . Eastwood sells it or you can order it from your local book store. Read it before you start wacking away and you will save yourself a lot of grief. Try to leave the fender on the truck if you have access to the dent from behind. It is hard to hold the fender, hold a dolly and swing a hammer all at the same time. Just not enough hands. Go slow and try to get the surface as flat as you can before you start laying on the bondo. The book is very good and it is only about $10.
Have fun and good luck. Gael
