I've got some minor rust bubbling on my '81 300TD. I'm not horribly concerned because it's taken 21 years for it to get that way! Typical areas, quarter panel behind each wheel well, under the lip of the tailgate. Floor pans look alright to me both under the carpets and underneath.
Next year I'd like to have the rust taken care of and have it re-sprayed original inca red...
Anybody have any experience with this type of work? How much will I be looking at?
