Rear inner fender decal installation

Greetings all. Does anyone have a technique for putting a flat decal on a multi-curved rear fender liner without getting wrinkles in it? Thanks in advance! 

Spray the surface with a mild solution of dish soap and water in a mist, lay the decal on the work from the middle out with a hard rubber blade to remove bubbles and water

Is it a decal or a sticker? If it is a decal, then Wookie's suggestion would be how I would go about it. If it is a sticker I do not think spraying soap/water would be the way to go.. Instead you would want it clean and dry before laying down the sticker.

If its a vinyl sticker, clean and dry the surface and get sticker warm using a hairdryer, work from the center outwards using a rubber pad and pressure to stop creases. You may need to reheat it to keep it maleable.

^^^ That exactly. ^^^
   There's not any significant thermal mass to a thin label; it'll cool almost instantly when it touches the cooler inner fender.  It helps to keep the inner fender very warm while applying the label to help keep the label pliable.  Take your time.  Enlist a helper to  warm the inner fender from underneath and keep it comfortably very warm to the touch, not hot, while applying the label.  A hair dryer is best to limit heat input.   A heat gun on low can be used carefully & sparingly from some distance.

The purpose of the soapy water "mist" is that if necc it allows you to lift the decal again (until it's dried out) without stretching or deforming it (may not work with all adhesive types used on these stickers/decals)

We're drawing a distinction between a water-wetted decal, and a dry, adhesive-backed (a.k.a. self-adhesive) label, or sticker. 

Question of nomenclature?

We'd guess most guys experience with decals are in the plastic scale model arena, wherein the decal can be smoothed & manipulated (within reason) once applied, as long as it's kept wet.

An adhesive-backed label (sticker) such as the one in OPs question adheres instantly on contact, same as electrical and cellophane tape.  Such self-adhesive labels are best applied to a clean, dry surface.

Jim I've never seen these body decals come in that cheezy "wet and slide" form, just not offered in that material. They do use that material in faceplate overlays like Diablo sells but i've tried those too but would Never sell/repair using those. TOO Shiny or glossy.  

Water under the sticker is a good play.  Auto graphics on the body are often applied that way.

Thanks Ed, this was the method we always used to install “ dealer fit” vinyl graphics on ltd edition models. They came with the car and if you messed up it took weeks to get replacements. This is also the preferred method for “vinyl wrapping” if you are less than expert or are applying a wrap with images or text that will distort if stretched unevenly.
Clay I had totally forgotten the old “airfix” soak and slide decals
PS: if the concern is that the water will stop them sticking? I have never seen a sticker or decal intended for external use that had water soluble adhesive ( any stickers I’ve removed needed lighter fluid to get the adhesive residue off)
