yeah the sanding/prep work takes time, then masking it off, filler needs to dry, sand it fill it more with more stuff it needs to dry, the primer needs to dry, the paint and clear can be done while all wet i think, and then that needs to be dry before you take it on the road.
if you had the day im sure you could pull it off, its not a huge area. but in the shop at his work i dont see his boss letting him sit on one car all day. unless you are paying labor as well to the shop. aka a paying customer. lol
thats not a huge area to deal with on your own. watch some repair vids and see if your up to it.
dont tape it off and paint up to the tape, it will leave a hard edge that is hard to sand down smooth. you want to feather the paint to the old.
im no pro by a long shot but ive seen it done enough. and if that was my car i'd give it a shot.
