Mick,
Primer should be covered up with paint soon after it is applied. If you use a
good DP-40 type primer with catalyst, these are supposed to be rust inhibitors
and are supposed to be able to be left out in the weather. Not that you would
normally want to. Regular primer isn't like this and should be covered by
paint.
