The science behind nail polish :)

And let's not forget the difficulty purchasing lithium batteries too.

If I purchase one from a seller here in the USA, they will not ship it via "air" and will only ship it via "ground" transportation.  When I do receive a new lithium battery, it has all sorts of scary, hazardous labels on the box.

I own 3 Nikon D1X bodies.   Most of the original nickel blah blah blah Nikon batteries for it are old and dead (or dying).  A seller in Europe sells lithium batteries for the D1X, but they will not sell one to me because there currently are no land/ground routes from Europe to Wisconsin USA (maybe when the Bearing Sea freezes over again  ).

Paul, it sounds as if you have enough isopropanol to last you a while.

However, here in Australia it is sold at paint shops as rubbing alcohol and it is also sold in electronics component shops for those folks that make up their own printed circuit boards - it is used as a cleaning agent in this instance.  Keep your container securely closed when not in use as it is very prone to absorb water from the atmosphere.

I have next to zero knowledge of chemistry but do know what i want. 
I tried in vain at the local apothecary to buy isopropanol for lens cleaning , even when i said that I was not fussy about whether the molecules were chiral or not they could not supply.Not just a case of the receptaries being used to sell boxed and readymade stuff rather than composing from basic ingredients, but probably some hypochondriac public safety institution thinking that some idiot might drink it. Luckily a chemist in Germany provided me with a bottle that will last a long time. Similarly it is easier to get lighter fuel than specifying very pure and easily evaporating octanol at the apothecarys`.

If a UV Light is needed, you can buy one from a Fly Tying reseller. UV paint is common when tying flies for fishing. Typically from $20 and up.
