I bought some replacement decals for the lighted areas of the playfield on my Space Station.
The original ones are quite old and brittle/cracked, one or two is partially peeled off and missing (see photos). Can someone with experience removing the old decals give me some tips or pointers as to what works best to remove the old ones and prep to put new ones on. My biggest concern is damaging the plastic and/or playfield.
Looking forward to hearing what has worked for people.
Thanks in advance.
