I've used UV DTF stickers from this company before. They cut out the print so images and letters individual stickers instead of the standard clear film, which is a nice option. The prints are a touched raised, I like the look.
To install you just pull the backer, place them, use the squeegee they provide and push them on, peel the top film. I start in a corner, peel slowly and if anything didn't stick, I can put it back down apply pressure and hopefully get it to stick. If it still isn't, I try from a different corner.
Just a heads up, they are extremely sticky. Once they touch a surface, they’re stuck. Try lightly spraying the area with water mixed with a drop of Dawn dish soap before applying, you will have some ability to move them. Also, it takes a minute to dry so I will apply, then move to the next pedal then when I am done, go back to the previous and peel.
