tip: skin thicknesses
Look in the front of the instruction manual for the parts index. This section enumerates every part number in the airplane, and it states what material the part was/should be made from. I've found this handy on many occasions. Now in your case, you want to know what .032 looks like? Go look at the various parts of the empennage and you can see what they are made from for comparison. You will find, for instance, that E-702 (Elevator Spar) is made from .032, whereas E-701-R is made from .020 thick material. So if you need .032, go find some scrap that looks to be the same thickness as E702....
