I use some 3M body protection tape on the bodywork above the boot Dzus fasteners to stop them scratching the paint. You will see where it needs to go and you have to replace it occasionally as the tape gets torn by the Dzus after a time. You may have to bend the retaining spring out, when the boot liner is out, to keep some tension on the fasteners or they can work loose. I don't think the Dzus fasteners are too much trouble for the bonnet, particularly with the G56 springs installed.......but I am an ex-aircraft engineer who had to wrestle engine cowlings back into place once upon a time.
