I'm in the process of staining/sealing cedar boards which are attached to
composite decking. Unfortunately, while staining part of the deck, some
stain seeped through the blue painters tape that I applied over some of the
composite. So now I have 2 challenges. First, is anyone aware of a
chemical (I've tried lacquer thinner without much success) or some other
process to remove stain from the composite? Second, is their a better tape
or technique to prevent getting stain on the decking material when the edge
to be stained is attached flush to the decking?
