Sorry dude but you could please fix up the spelling and grammar a bit? It's kinda difficult to read :s.
Getting back to the topic, the type of primer you use is somewhat important for wear. Using craft sprays will shorten the life of your paint job. If you want a matte look, there maybe multi-surface heavy duty paints that replicate a matte finish. If you've already primed it I don't know if its smart to remove it, but just try to make sure your primer is a type that is recommended for outdoor/heavy duty use, even if it means the finish will not be exactly how you want. Function>Form.
If you want actual products, stuff like this -> http://www.krylon.com/products/matte_finish/
works for most plastics. Just not sure if it will work with a primer.
