Mustafa,
I highly recommend the Zaino products. Bill at NSXSC did a test not so long ago...
http://www.nsxsc.com/nsexcitement/waxtest.html
This test was done prior to the release of Zaino's new ZFX additive which makes the product all the better (dries faster, better shine, eliminates one step).
I would hold off applying a conventional wax (you would just have to remove it prior to applying Zaino) and give Zaino a try.
I'd recommend the Z5 (with the ZFX additive), the Z7 car wash and the Z6 spray (for in-between touch-ups after you wash. They also have a clay bar that works very good as well. If your paint feels rough - then I'd recommend that step.
You can reach Zaino at...

You can order directly, or give them a call and find out the nearest reseller to you. More often than that not the "reseller" is a "car guy" or a collector who loves cars and became hooked on the product. I've found my local Zaino car (ex-detail shop owner) to be very helpful on detailing questions, etc.
Here's the basic process...
1. Wash car thoroughly with DAWN liquid dish detergent. Do this to remove all old waxes, but do it only once. Wash it with Z7 car wash after the first Dawn wash to remove any Dawn residue.
(And for you, use the clay bar during this step according to instructions. Do not use any clay bar on a dry surface. Clay always needs to be lubricated with a "soapy" wash rinse. I used the Zaino Z7 mixed with water in a spray bottle.)
2. Decide between Z2 or Z5. (I recommend Z5 for your car).
3. Mix ZFX with either Z2 or Z5 (according to directions: about 4 drops to 1 oz. Sal sends you a nice KIT to do this with.
3. Apply this mixture VERY VERY thinly to your car. Do this out of direct sunlight.
4. Remove the haze using a clean 100% cotton towel (Cannon is the best). Polish as you remove.
You're done, although you might want to apply the Z6 spray enhancer afterwards. It helps the shine but also helps to cut down on static and dust. Very nice.
Wash the car with Z7 and reapply the Z6 after each wash or as needed for touch-ups.
Have fun!
