paint flaking off

Have a 1996 white cobra. Anyone where to get a ready made can of touch up
for it.
I believe the code is zr1 or similar.
Anyone else have this problem? It started on the doors when I pulled my
racing numbers off.
Paint must be chemically changing as it seems very easy to seperate the
finish from the primer.
The roof was next when I tried to suction cup a dent out.
Maybe I'll just put some strips on it to hide the peeling.
