Look out for the bodywork surrounding the external door openers. The chrome plunger/button is on a neck and enters the fibreglass bodywork through an opening which seems prone to cracking - mine cracked and I never figured out how to successfully repair it.
the plujer slides in a reasonably chunky alloy sleeve that is bonded into the body . The cracking will most likely be where the gel , or filler , blends to nothing . It would probably be best to blend it in further down the sleeve .
