yes it is they do not wanna come off.Removing stickers is a chore! A heat gun helps to remove the sticker but the glue remains. Goo gone or lacquer thinner works pretty good but it is a lot of work.
im using a hair dryer and goo gone it is time consuming but its getting there. I may try a paint removing recipe my buddy told me about to strip the frame to bare metal but again that can be a huge issue more then I wanna deal with .
we shall see
