I've only seen fibreglass bonnets do this too; usually once the wind gets under them at speed.Never had that issue..is it a fibreglass bonnet?

No spacers fitted, just seems a lot of movement. At the front near the catch seems fine, just up near the hinges has more movement than expected.I've only seen fibreglass bonnets do this too; usually once the wind gets under them at speed.
I think they flex a lot more than steel and will even try to bull bonnet pins out of the body.
Unless you've got spacers installed and they need tightening maybe?
