-I have noticed that for obvious reasons military aircraft paint the wings of tankers and large bombers. However why is it that airlines do not paint the wings of their aircraft ? Also since military fighters and bombers show no silver does that mean they do not have ?

Paint means weight... Unpainted aircraft, like American Airlines are lighter because their paints are generally restricted to the "water line" stripe and the airline's logo... and paint is used for anti-corrosion purpose, i.e. belly areas...
Most airliners have painted surfaces on the wing, however, as an example, to indicate the "walking path" or "no step" areas to maintenance or crews and passengers in case of an overwing exits emergency evacuation...

I was visiting Fokker in the early 90's on a project involving the F100's for American. They were just polishing up a brand new F100 for US Air, after completion of test flights, getting it ready for delivery. As we watched, the conversation naturally turned to the merits of paint versus polish.
My colleague's (the Fokker engineer's) opinion was that the bare aluminum is a pain in the a@@. The weight savings seems to be outweighed by the cost of keeping it polished and free of corrosion. But he did not have financial data to back it up, he was just expressing a common opinion among his co-workers.
I noticed also that many (maybe most) aircraft have large areas on the wing upper surface (maybe on the lower, too, but I can't see that from a window) painted light grey, with the markings that B747skipper mentioned above.

All 3 of our (USAir) paint schemes have light gray paint on the upper and lower wing surfaces. The leading edges are polished. I've always assumed that all airlines had painted wings. Now I'm starting to wonder.

Our aircraft wings are white.
We had a bare aluminium finish on our freighters but in the hot sun, where we fly, it got hot inside (and its a freighter, so depending on what we where carring, it could stink up real bad) We have since painted it white, and it made a difference to the inside temp. But the boss did not like the look of a white fuselage and silver wings looked so he said paint the wings as well, so we did.
I'd love to say it we painted our wings due to technical/cost resons etc but if the boss wants it a certain way, he gets it that way (and you be surprised how many things in aviation are a result of one mans wish)

well COSYNC depending on the size of the aircraft, paint can add quiet a bit of weight. I am open to correction but a B747 can have paint weighing up to 500Kg on it with an A319 coming in at 200Kg. (paint dries so its not simply a case of counting/weighing how many litres of primer, paint etc you put on the aircraft, so as to get the paint weight)
In fact it is common practice to reweight your aircraft after a complete paint job so as to recalculate your weight and balance and you must rebalance your flight controls if they have been painted. (The aircraft maintenance manual specifies limits etc) Some companies add even extra weight by simply repainting over existing paint, but save time and the expense of stripping etc. Our last aircraft in the shop had 4 layers of paint to strip off (added two weeks to the down time of the normal aircraft paint job time)

The philosophy or methodology behind the painting of the wings actually falls back to the manufacture. Regarding Boeing aircraft (commercial airliners) I have never seen an example of an aircraft that did not have all surfaces of the wings painted except for the LE slats (occasionally those were painted also). The Douglas products that I have painted (DC9/MD80 and DC10) only have specific areas painted. Why the different approach? This is a good question for the manufacture.
The types of product applied to the wings is more airline specific, most choose to have a aluminized coating (trade name Aeroflex) applied, these are specifically formulated to withstand chemical,fluids,etc.. that the wings are exposed to. It usually maintains a nice "silver looking" appearance that many mistake for a bare wing.
In other cases they will choose "appearance" over practicality and apply a hi-gloss polyurethane.
