A few weeks ago I did my seams and surrounding three inches, at the typical
rust spot where the camper stuff is welded in on the drivers side. I ran out
of time after applying primer/sealer and thought thats ok to wait a while at
this stage.......
now we had two days of solid rain, and I have micro bubbles under the primer
about an inch away from the seam, and worse, something slightly rustcolored
at a few seam spots.
Obviously I have to redo a few things, but I was wondering whether my
assumption that primer sealer is weathertight was wrong, or if I did the
whole thing wrong......

thanks
