I didn't know what a "Slam Panel" was, so I googled it. (Radiator support/surround that the bonnet latches onto)
I concur, the paint on there is not great, mine is discoloured, and I thought this was probably due to having previously (prior to my purchase) been left standing for quite a while (in wet weather) and presumably showing signs of surface rust which had been "cleaned off"... prior to sale.
I was thinking to give it a coat of Waxoyl or similar as we plan to keep the car for a while but if the issue is the type/colour of the paint, rather than the after-effects of surface corrosion, I might be OK.
Cheers
