Well after 24 hours the bubbles shrunk back almost flat but there was a little bit of drumming underneath each area. So after much discussion with DB and Adam it was decided to try a hot iron on the spots to try and stick them. With much trepidation, as the plastic edging was near the spots, I applied some heat and seemed get a bit of improvement. So stuff it - turned the heat up on the iron, got it nice and hot (like sticking veneer edging strips) and bingo it has worked and stayed there for 24 hours.
So now it's time to get back onto the project.
