well if you got the paint job done professionally and its peeling after a year id check back to see if they warranty there work. cuz if its peeling after a year thas a shitty ass job.

i wouldnt recomend spraying it with rattle can clear ..your best bet would be to wash, wax and lay on the wax that'll help it protect the paint and stuff for a bit. other then that you can't really do much unless you go and get it sprayed again.
