There are plenty of 'matte' or 'satin' clear coats. What makes something shiney is a smooth surface. Clear Coats increase shine as they are a good self-leveling material. A little rubbing on top of that to smooth it out even more, and it shines like the outside of the car.
As for the mattes and satins, they simply do not 'level' as well, so that light is not reflected off an even surface, thus reducing shineyness <-- that's a technical term

. Putting a clear, regardless of satin or gloss, will help the durability of the paint.
Keyan- I expect it to hold up just like the outside of the car. It's basically the same paint method as is used on the autobody work. The wax won't melt, just like it doesn't melt off the outside of the car when it sits in the sun.
2GTS- If your serious about looking for some help (or someone to do it for you) you're only like 30-45 mins away from me. So long as schedules permit, I'll give ya a hand.
