Add to cart button css change for one specific product only

Hi there,
i would like to know if its possible to modify a css style and text of ‘add to cart button’ of one specific product only in woocommerce!!

this is what came to my mind and obviously did not work:-)

.woocommerce .postid-558 .add_to_cart_button {
width:100%;
background:#539DC2;
height:1px;
font-size:17px;
font-weight:lighter
}
