I've  found a water/rain leak in a seam on my van.  Cracked OEM  sealant
letting in water but don't see any signs of rust. I just want to  reseal the
seam with minimal painting or rework.  Is this possible or  should I be
ready to grind, sand, seal, prime, AND  paint?

if you dont have any rust, just reseal it.
