i'm fitting a gloss white kitchen and it comes with end panels to
stick on to an end run of units. they are quite heavy.

has anyone done this before and what method did you use to stick them
together? i think they could be screwed on from the inside with the
right length screws, or to avoid screws, some sort of strong glue and
clamped for a day or two.

i'd like to know the proper way of doing this and what product to use?
i've just had a look in screwfix and theres about 50 different grab
adhesive type products!
