the fender i got from the junkyard was an older fender so it had some extra side reflectors and an extra antenia hole... so i got to play around a bit with shaving stuff DIY style... and its pretty easy if you have some patience
just start by sanding allllll the paint from the area of the said item to be shaved... then take a grinder and quicky grind the paint from the back of the hole u want to shave... tack weld a small piece of steel sheetmetal to the back of the part, making sure before hand it is bent correctly to fit reasonalby flush to the piece.
let it cool, and thourougly clean the area with some "prep-all" or other wax - grease remover, this will help the filler adhere. make sure to hit the area with either a grinder or course sand paper before cleaning it so it is nice and rough...
mix up the filler to its directions, and liberally apply it to the area, making sure to work it enough that there are no bubbles left in it. also make sure that there is excess over the area... wait for it to harden, then carefully sand it back down to flush with the fender using either 180 grit or 400 grit on a DA, air sander...
now your ready to once again clean the area with more wax - grease remover, (even your hands secrete oils that can interfere with the adhesion of paint so don't fondle it after you clean it lol), and primer it... do not paint so closely that it runs, lots of little coats are better, and primer dries very quickly so you can move around rapidly and usually it will dry right behind you.
if you can't see the patch thru the primer, and it feels totally smooth, your ready to repaint the fender.
not too tricky, although if you are not experieanced in body work i would suggest going to a junkyard, getting an EXTRA body panel, and trying it on that one first.
