Thanks Peter,it was a job I don't think I would have contemplated doing before,but I figured even if I got in over my head someone(like you
)would be able to give some more direction.I now feel confident to start on the rocker panels,I have some delamination of the undercoating around the jacking holes.BTW what is the primer that MB uses?That stuff was like brand new and very tough under the spot welds.Even the new parts were coated in it,at first I thought it was just a shipping primer but when I tried to strip it to weld to I found it was really on there.Now someones going to tell me that it's weld-through primer
