Effective windshield watermark remover?

[dr. d]

if you want to do it right, then you must do it by yourself...

the assumption is,
"you know how to do it right".

many years ago,
for two hours, i was lying down under the car, trying to get that blasted steering box down.
i finally gave up, and drove to the hilera of shops near the residence.
the mekaniko there did it in 15 minutes.
i was just so happy when i was paying the guy.
