I've found WD40 to be damaging to some plastics over the long term. A few hours or days is fine as long as it is washed off afterwards, but long term exposure (as in months/years) will have exactly the effect Jonnybear describes in post 8.
We had a TV in the workshop which had been treated with WD40 (for a crackly volume control) over a period of years, and the plastic in the area of the V/C was crumbling quite badly.
This may be an extreme case, but I'd advise that all traces of WD be carefully cleaned off after it has done its job.
