cooling + ac output

[Brooks Ellis <brooks@frii.com>]

Is there anything special we aught be doing in the hot hot weather to take
care of our cars? (Using higher octane fuel currently)

I saw some generic 'water wetter' in the local auto parts store; advertised
to keep temps down 20-40 degrees (C?) in trucks and RV's when going up big
hills, or hauling big loads, towing.. etc. 

I didn't buy it, it was $25 for a can, and am thinking money better spent
on real water wetter.

Another question - my AC doesn't seem to be cranking out as much cooling as
a generic rice grinder, is this typical? Do I need a recharge?
