I am wrapping a trailer this afternoon and it has a crap load of rivets.  Normally i put some primer 94 on the rivets to help keep it from lifting over time but wanted to know if this is a waste of time.  I have only done a few trailers and they didn't have that many rivets so this one would take a little while to primer every rivet and wanted to make sure i am not wasting all my time for nothing.  Any comments would be great.  Thanks
 
Josh
