Paint

Hi

I am restoring a 2 door 1100 the problem is the paint on
the car is fairly neat, but has been reprayed sometime.

In places the paint is chipping off revealing the galvinised body
with no visible primer / undercoat. These areas are mainly around
doors, windows & roof channels.

What would you advise fix & primer these areas & prep the car
for spraying

or stripp all paint & then re primer  :dontknow:
thanx
