I have got a b&q kitchen, when the chap came out to measure he said we'd have a small gap to fill requiring a filler panel, however, when I've put the units together I've got an 8' gap!! Can I cut a high gloss door to fit this gap and what about the end I cut through?? Will it expose the pressed wood of the door?? Help would be very much appreciated cos I'm up to my neck here!! thanks.
