Tom, Brad etal.

Make no mistakes.  The stress fractures commonly found along the bonnet
latches are not from any sort of vibration.  They are caused by using
the bonnet latches as handles to raise and lower the bonnet.  The
correct method of lifting the bonnet is by the wheel openings and after
the middle of the bonnet clears the cowel, by that point.

This is a common malady found not only on Spits but also on Heralds
because they share the same sort of bonnet latch mechanism.

So, if you use the latch as a handle, stop immediately.  If you don't,
then don't start and certainly don't let anybody else.
