InvisableShield has a product to cover the outside of the MBA.
To protect it from scratches, and to give the case a tacky feeling, reduces chance of dropping.

Assume the product is as advertised.

My question is. When my MBA does processor intensive work it gets pretty hot. Photo processing, playing videos, etc.

Will the invisableshield trap some of the hot air that warms up the case, instead of letting it radiate from the uncovered MBA?

I like the protection angle, but not if it retards heat disposition.

I'm debating now whether my MBA 1.6/80 runs hotter now as compared to pre-Invisible Shield. I did not think to pay attention to fan speeds and temperatures. Now I have the IS on the top, bottom, and wrist rests and my fans routinely run up to 6200rpm even though I've installed SMCFanControl and Coolbook.

I'm debating whether to remove the InvisibleShield on the bottom, but concerned that once I do I will never be able to go back. I have to assume that IS impedes heat dissipation a little bit, but is it enough to make my fan cool off. If the fan is going to go at 6200rpm regardless, I'd rather leave the IS on.

Anyone?

the fan would spin up to 6200 RPM constantly whether or not i had the IS on the mba. i don't think it gets in the way of heat dissipation because you can still feel an incredible amount of heat on the bottom when the cpu is on full load. i monitor my temperatures constantly and my mba has never increased in temperature because of the IS.

I don't have an IS, but I do have a BSE on my Air.

I don't find it runs noticeably hotter. Anything that covers the vents at the back will dramatically and probably catastrophically affect performance but all these skins do is decrease surface heat dissipation a little.

In any case, even a moderate increase in temp. would probably be a worthwile tradeoff for the protection the skin gives.

I have the BSE on my MBA. I was concerned about temps as well, so I logged before and after temps.

I have seen absolutely no increase in temps after applying the BSE skin. So I wouldn't be worried.
