Bad paint job

It all depends on what you are willing to accept in the way of quality. Obviously since your clear is peeling, quality is going downhill, and if you want to just get by for a few more years, then you want to keep it as simple as possible. I do not recommend trying to sand/feather the peeling clearcoat edges, a typical two part clear coat is thick, on average about 2 mils, and basecoat is very thin, more akin to a dye, and I guarantee that you will be sanding through your color and exposing the primer below it, making for an unsightly bullseye, just like @j_anderson experienced.
I would do what @jeff alder suggested, just go get some cans of spray clear, scuff sand the panels you plan on spraying with a grey scotchbrite or finer(paying considerable attention to the edges of the panels), mask the areas, clean the panels with a wax/grease remover, do NOT use paint thinner, you will remove the base color that has been exposed, blow it off and tack with a tack rag, and then spray the clear over the entire panels. Good prep is key to the new clear sticking to the surface, or else you will be facing the same delamination problem with the clear you have just sprayed and it will peel off too.
Your skill/environment sprayed in will determine how good or bad it looks, but dont expect a bodyshop quality job, but it will get you by for a few years.
Hope this helps.
