I've been using those magnetic L plates for a while now and noticed some very minor scratches on the paintwork, mainly on the bonnet. The other day, I was plodding along the A2 at 70 when one of the plates flew off. I just noticed today 2 rather large scratches on the bonnet ( i can see white showing) which I'm sure was a result of the plate being whipped off. Can I do anything to get ride of them/hide them? My test isn't for a couple of months yet so its either stop practicing or getting some tie on plates.
