I would recommend the new class of glues: the "MS polymer" ones (MS for Modified Silane). They are incredibly strong, but leave you some time to reposition (depending on the brand), are solvent-less (do not damage the board if you want to remove it), and use air moisture as a hardener (thus some humidity is no issue). They take some hours to get full strength (depends on the brand). Also they stay supple, which is great for use with pads.
