I have some 3mm thick rubber matt, trimmed to shape under the front edges of the grill cowl, to act as a pad between the cowl and body. It can be stuck in place with Super Glue. The bonnet Dzus fastener springs get bent inwards and weaken their grip over time. If you use a small screwdiver to carefully bend them back out it will put some more tension on them. This will help stop the bonnet moving about, squeaking and wearing the paint finish. The 3M protective tape is easy to replace as well and will help save the paint finish.
