reforming capacitors, worth it?

One though occurred to me just a few minutes ago. Most failures in capacitors - actually almost all pre-IC components - can be boiled down to impurities getting into the innards of the part thru failing seals. This is documented in military and trade rags, as they found out in the jungles of the Pacific during World War 2. With capacitors, the problems seem to be the dielectric (oil) getting out (see my previous post concerning Vitamin Qs), or moisture getting in. Either way, the dielectric is poisoned near the weakest part of the cap's structure - the edge of the foil, specifically where the leads connect to the foil. I can not see where reforming an electrolytic capacitor will do any good for the seals. If the seals are drying up, cracking, shrinking, expanding, or in some way not meeting spec, the crap is going to get into the innards of the capacitor and lead to a failure. Other than a complete rebuild, I doubt any seals can be repaired. And if you are going to do a complete rebuild, you might as well run the cap until it fails. And unlike an inductors that can be baked to drive off moisture, capacitors do not do well in the oven. -- Will
