[Boatanchors] Electrolytics.

[parinc1]

I have found by far the best, least expensive and easiest solution is to use a razor saw  to open the can at its base, throw out the junk inside and install new  electrolytics. A bit of foam rubber to stabilize the caps and re-epoxy the bottom to the can. I then put a label on the top of the can with the date I resuffed the cap. See images 4, 5 and 6. as an example:
