2K primer over whole panel?

I am working on the roof of a truck, it is in good shape other than 2 small spots.
So far I have 2 coats of epoxy on the whole panel, with the filler in the 2 small areas.
My next step is the 2K primer. Is the proper method to spray the whole panel or is it acceptable to just do the spots then follow that with the epoxy reduced as a sealer?
Thanks.
 
Which ever you prefer. If you want to spray the entire panel you can then give it one last blocking before sealer and paint, your choice either way will be fine.
 
Thanks.
Also one more question.
When I am done wet sanding the 2k primer, how long should I wait before I spray the epoxy sealer?
I am worried about trapping any moisture that may be absorbed while sanding.
 
you can blow it off with compressed air to help it dry out.
or put it out in sun.
just remember if you dont spray your next product within a 24 hour period, you must sand/scuff 2k primer beforehand
