Gear lube, transmission fluids, engine oil, power steering fluid, and alike all are formulated for different task. It's just not good to inter change. If one could be used in place of another. The manufactures would rec amend it in the manuals, and containers would list it. As far as stop leak products. There mainly designed to soften up rubber seals. I've seen transmissions and alike apart after use. If you are just trying to get a few miles out of something, then dump it. Their fine. I'll never use them on anything that I'm going to keep. You just might fine that the problem well just pop up on a lonely stretch of road some were. I'd suggest, just fix it correctly now.

I agree with you that the "mechanic in a can" is not the way to go except in some emergency situations. There are exceptions where they are factory required. For example the Cadilac Nothstars using Dexcool have a factory sticker under the hood saying that you must add 3 GM coolant suplement tables (Bars leak) at each coolant change. Subabu's require a factory additive, liquid form I believe, with coolant changes. Oddly (or not) both these cars were plagued with coolant related head gasket histories. Also be carefull with the zddp craze as too high a concentration becomes corosive to metals and GM warns of cam lobe spalling. A case where too much is not better.
