The suction cup method can work well on semi large shallow dents like from some one sitting on your hood.

There is a heat gun, dry ice/duster method that supposedly has good results on some dents. I have not tried that method yet but hope to try it on my dads car later this year. That method you heat the dented area well with out burning the paint and place the cold source on the hot metal the difference in temps causes the dent to pop out. Search on google before performing it though.
