Depends on the severity and colors.

Tamiya gloss white paint has been very good for me when it comes to restoring white die cast Autobot cars such as Jazz, Prowl and Red Alert. Tamiya gloss red has also done wonders with red die cast cars such as Sideswipe.

The trick is not to paint over the whole surface but with a fine brush, you simply cover up all the scratches. Once it dries, the result always amazes me as it blends in really well; what once looked like a horrible surface with multiple scratches ends up looking very smooth and minty and with minimal effort too.

Unfortunately this methods fails badly when it comes to plastic surfaces so you are better off using H2O2 or if the plastic originally had painted detailing, the matching tamiya color with a thin brush. Reprolabels also do wonders when revitalizing old toys.

WARNING: Don't spray a G1 metal surface with spray paint, it will act more like paint remover and 'wipe' much of the paint off. G1 Die cast isn't really painted on and looks more like a weird form of vacuum metalizing as the 'paint' is 'wrapped' tightly around the metal surface and when it chips or flakes, it is in noticeably thick bits.



BTW: Since this is a 'repair' thread it will most likely be moved to that section in the near future by one of the admin staff.
