hey i do collector car restorations for a living so this is exactly kinda **** i do on a daily basis ( not unshaving doors on a honda but making and putting in patch panels), metal working, blocking, painting, polishing etc.. since you have an extra set of doors, take a piece of poster board and make a template of the outside handle, making a reference with say the window line and edge of the door ( so you know where exactly to position it on the shaved door). then come in say a half inch smaller than the actual size of the handle ( just to be safe) and start digging that body filler out. before you start digging. use a fresh razor blade to carefully score the paint around the area where you plan to dig out. thats why i say dig a smaller area than the actual handle size at first so you can get down inside there and see what you are up against. by cutting the surface and staying inside the lines you wont screw up your paint job as bad as say getting out the da and going to town on it. if the metal around the door handle is screwed up too bad just cut the handle section out of the spare doors you have, cut the same part out of the shaved doors and weld the new patches in place. KEEP THE METAL COOL whenever welding on thin stuff slow and steady wins the race and keeps you from having to pile bondo sky high on there after you are finished and spend the rest of your life blocking them trying to get them straight for paint again. keep a blow gun or really wet rag to quickly rub over the weld after each tack. unless you are god or super man it is impossible to run a non stop bead on sheet metal without it melting and or warpping. any other questions i'd be glad to help share some knowledge.
