[W126 Coupe] Rear Window support panel

[Dan Gardner]

Hi Folks

    I thought while I was waiting for a replacement speedo,it would be a 
good time to check the rear panel under the rear screen,luckily there only 
seems to be some surface rust,I know from the cars I inspected prior to this 
one(15)most had horendous perforated rust.
    Its a difficult area to derust as access is only through the holes did 
try a pencil style wire brush with limited sucess,sandblasting would be 
effective but very messy.

    I am interested what other members have done as far as rust proofing is 
concerned,its quite tricky as water has the potential to leak from the 
window and start rusting behind any new paint or sealer.
    Most of the commercial "rust dissolvers" seems to be phosphoric acid 
based which if not neutralised fully after treatment could makes matters 
worse.
    If anyone has a real "bullet-proof"solution I would love to know.
