we use a stripe eraser made by 3M or other companies its a small rubber type tool with a 1/4 stem attached to it. air tool or drill works fine just let it do its job by running it over the stripe. the good part is that its removes all the glue from the stripe too! leaving a very clean surface. but it also wears out. you should get your whole boat out of one.
but then again we also use a heat gun. [old school ]
