Nooe. All you need is some warm water, a pair of scissors, a paper towel and some tweezers. Trim as close to the art, soak in warm water til the backer starts to slide and slide the decal onto the surface. Blot dry. Then you can clear coat over them. Instructions are included.
DefineLuck yes I sell those waterslide decals separately for 15.00. If you are interested pm me your email address and i will send you paypal info. Once I receive payment i will drop them in the mail!
Thank you for your interest.
