Well, you start going on one of these MB's and it becomes a treasure hunt.
Yesterday I was bolting the rt frt fender back down after body repair and paint and I began eyeballing the whole inner wheel area for issues and noticed the major rust and rot along the under bumper apron/valance strip.
That of course led across to the left frt fender and the same rust rot condition.
So I removed fender liners and bumper end rubbers which exposed the rusting bumper rubber brackets.
I spent the rest of the day doing rustoration with POR 15 products.
Today, I began body and final paint work and noticed a puddle of antifreeze beneath the rad.
I think my demo and prep of the rust may have shaken or somehow moved and stressed something in the rad and opened a small crack or hole.
Which leads to my question.
Should I just buy new or is a local recore a good option?
I will post this as a separate thread.
