Can't buy it any more in the pharmacy.

Greetings fellow club members!
Back in the 80's when I was still milking cows, I was able to order Tincture Strong Iodine from my local pharmacy. I used it for sanitizing my milking equipment, and it didn't take much for that purpose. It might be worth your while to go to your local pharmacy and see if you can order it. I don't see why you would not be able to still get Iodine. As to the issue of Iodine being used to free up rusted nuts, bolts, and stuck engines, it's an interesting theory, although I've never tried it myself, and quite honestly, this is the first time I've heard of using Iodine as a rust penetrant/dissolver. And trust me on this--I've heard of just about every concoction known to man to free up a stuck engine. One more thought--have you considered using a commercial penetrant known as Kroil? It's supposed to be the best there is, but then that's only what I have heard.
