My Rollergames has some worn insert art (probably from when someone lifted the mylar off). I have printed (using a laser printer) replacement insert art on some water slide decals and they apply nicely, but to no surprise don't stay in place for very long. Is there something I can apply to them (underneath) and/or on top of them to get them to safely stay in place on the playfield? I don't want to clear coat the whole playfield, and while it plays great, the pin is definitely a players condition so it doesn't have to be perfect, although still want it to look decent. If water slide decals are the wrong approach here, what should I use?
I can print using an ink jet or color laser printer. Thanks in advance for the great advice I always receive from my fellow Pinsiders.

Great suggestions! Appreciate the tips.

Good catch!!! Yes, water slide decals. That actually makes more sense. Just corrected the wording in this post/post string.

Just wanted to thank everyone who gave me advice on this thread. Installed new water slide decals and then put some clear Mylar over them and it came out great, and the decals should now be nicely protected. Thanks again!
