LT-26 immersion Tin claimed 100 microinches of Tin, and in fact, in my hands,
put down 35-40 microinches, at 160 F, and 10 minutes.  And in fact, gave a
good 30+ days of solderability.... and I suspect, (without even realizing it,)
they already had "solderability preservatives" built in..

I have done the research on this....
