From my bike shop days installing handlebar grips... For interior art blades I use a little soap and water on a few paper towels. Get the towels wet, get a dollop of soap(probably not Lava soap, etc), can be liquid, foam or bar soap, the towels need to be wet and slippery. NOT dripping wet.

- Lift your playfield to upright service position,
- peel your art sticker and set sticky side up,
- get the cabinet sides you can reach with moisture and soap...don’t worry about every inch
- generously wet/soap the sticky side of the art blade
- position the art blade on the cabinet
- the moisture and soap make it easy to slide the art a couple inches in any direction
- when position is perfect use these to protect your work https://www.pinballlife.com/interior-cabinet-protector-blade-set.html
- raise and lower playfield as needed to press out any bubbles and finalize position
- give it a couple minutes to settle in
- repeat on the other side

This doesn’t make the pin lighter for moving... but is an easy way to apply side art with or without the playfield in.

YMMV, so even with simple, natural hand soaps, this may not be for the minty-mint crowd worried about perfect everything. My experience across my machines is easy on and off with little residue and no impact to cabinet paint. Made it easy to swap and view the variety of art blades for Star Wars. It was especially helpful for my older machines like Funhouse that don’t have perfect cabinet surfaces to start with.
