Charles, look up Vapor Apparel - they are perfect for sublimation

I have hear that you can use for cotton t-Shirts an Poliester spray, so you apply the Poliester spray on the Cottton T shirt and you can sublimate without any problme on it, is it true?

True, there are sprays out there designed for this puprose, but many of us tried and failed to get a retail quality result printing on cotton treated with such spray.
The spray creates a kind of thin film on top of the fabric, when sublimated it gets stiff and sometimes yellowes, after wash it cracks and fades. It doesn't look or feel nice.

Doesn't sublimation fade with exposure to the sun moreso than other print methods??

It definitely doesn't fade more than other printing methods - sportswear and swimwear are mainly printed by dye-sub method and I'd say these types of garments get much more sun exposure than other types of clothing.
A lot of outdoor advertising - banners, flags, umbrellas - done with sublimation too.
