I always wanted to find the one which melted Limburger cheese the
slowest.

LOL!!!

You aren't far off Val.  Old mechanic's trick on diesel engines is to put a
gob of lubriplate engine assembly grease on each exhaust runner.  The one
that wouldn't melt the grease and trickle away was the bad hole.

Nice to hear of the accuracy of the IR thermometers.  I use mine primarily
for tire temps on the race car, but there are a myriad of tasks from setting
the infloor heat loop flow rate in our house, to diagnosing glow plug
function.   So would it be correct to assume that the correct emissivity
could be attained by painting everything before you take a reading?  You
know, shiny metal surface give it a whoosh of black spray paint, then test
when dry; seems like the neighbor's kid has a fever when over at the shop,
little diagnostic whoosh of some skin tone spray bomb, and you get an
accurate reading?  that sort of thing?
