don't peal off all the backing in one hit usualy help's
Method that's worked well for me in the past is the peal the back a tiny bit and apply the decal, this allows for earlie adjustment so its where you want it, once your sure its right slowly peel the backing off as you slide the decal on, the best way to avoid bubbles is to use a flat edge on the surface as you peel the backing off, try your credit card!
If you do get bubbles you can eliminate them by using a flat edge and drawing them out to the edge, or use a pin and pop the bubble and push it flat, if you have had bubbles i would sugest a lacquer coat to harden the decal stop it peeling back later on once the stickyness starts to age.
If there water slide transfers you can either put them on in a bowl of water so you can position with your finger or a pair of tweezers or do the same out of water just dripping bits on as you need it, dry off with a paper towel, dabbing not wiping.
