Sorry to hear you had trouble applying your stickers. It would sound like there is a coating of some sorts on your boat, especially as both lots of stickers came off. Did you clean the area with Prepsol or anything similar before putting the stickers on? Did you put them on using any water ? and if so did you wipe out all the water using the squeegee and then wait a period of time for the stickers to completely dry before removing the application tape ?
