The other side appears to be okay and the problem has not shown up on my '00 Outback. My body shop guy had never seen this before, but a Google search indicates it is not an uncommon problem. Seems that welds/seams are not quite right, which allows the dread water in. Only fix I have seen is to cut out the affected area and weld in a section scavenged from another Baja/Legacy/Outback. However, I'm not sure this will permanently resolve the problem.
Anyone with first-hand experience with this issue and its resolution?
