i've just removed the bumper trims and dorr trims of my three door hatch
to remive the bumper moulding i removed the whole bumpers
front bumper there are about five plastic rivet type things three bolts on the under tray and two screws in each wheel arch. oh and there are two hidden clips above each light but there are holes in the bumper to push a screw driver through to release them and the bumper comes off, then it is just a case of popping out the mouldings.
the rear bumper there are five screws underneath the bumper and three in each wheel arch and two of those plastics clip things hidden behind the rear lights which you will also have to remove. you then unclip the bumper by pushing the the top of the wheel arch towards the front of the car one side at a time then the bumper comes off and pop out the trim but also remember that the number plate is attacted to this rear trim so you will need to refix it somehow, mine is stuck in the rear window at the moment.
on the three door to remove the front door rubbing strip open the door and remove a rubber grommet from behind the rubbing strip and use a screw driver to pop out the retaining pip which is plastics and attached to the back of the rubbing strip, then slide it backwards, i found that holding the bottom out slightly while pulling worked. with regards to the rear quarter rubbing strips i found these very difficult to remove, the haynes manual says open the door and slide them forward but this dont work as the trims wont do this after i broke them both so to be fair i dont know how to get these of with out breaking them as the grooves in the back of them dont all go the same way, there are three clips two grooves go one way and third goes the other, i ended up supergluing the lugs back together.
