As part of trying to stop a roof leak my husband put Eternabond along the whole roof line of our Adventurer. He did not clean the part where the tape adheres to the gutter and now all that is coming lose and between the look of the lose glue and the dirt it looks awful. The tape also has bubbled up. We would like to strip the whole mess off.
What is the best way to get rid of the glue deposit? At some places the white plastic part comes off, leaving the glue deposit behind.
