I even used some crocrous cloth wetted with paint thinner and eventually I got it all off of all the surfaces, the gasket lands, coolant cavity & plate, screw threads and screw holes clean. I wonder if CLR would be the best thing to use???

Anyway, after cleaning I then washed all the fromerly corroded surfaces w/steam distilled water & dish soap and then rinsed and used acetone as a final de-watering wipe. I used the LPE paint to refinish my stuff. I also didn't have any pock-marks than required any body work to make smooth.

I didn't paint the gasket lands, I masked them off on the T/B and the cover plate I only painted the top side. I used rtv to coat the gasket on both sides and reassembled. It's been since October of '05 and I haven't had the corrosion come back....but I do use steam distilled water to mix down my coolant and it gets done every two yrs without fail.
