I completely rebuilt the aluminum water jackets on the water pump housing of a ford 150 that was corroded badly. I sanded with a dremel the damaged sections then molded the thin walls and continued building them up until I got the general height of the wall. Then I sanded the whole gasket
surface flat with piece of plywood and sandpaper.

I polished and carved out the repaired sections with a dremel to the general shape of the original wall thickness. It was my friend's truck and he didn't have any cash. I expected it to last till his next pay. That was 3 years ago and he's still going.

I have a question though as I don't have the stuff anymore. What is the pressure strength of JB.? I'm thinking of using the stuff as a
hydraulic seal(gasket) between 2 plates that are machined flat. Oil passes through a drilled passage between the 2 plates, pipe on one plate, a connector on the other. It would be thinly applied all around the edges for a box-in seal before bolting the sections togeather. I expect most will squeeze out to a few microns. Oil pressure will be 3000lbs. If it works it will be a cheaper substitute for Mylomar but won't be able to seperate the sections as you can with Mylomar.

thanks.
