I've been assembling plastic Tamiya models in the past. Got recently interested in diecast models and will need some advise. I have compressor setup, just not sure what to use on metal diecast models for primer and paint. I still have plenty of Tamiya enamel paint however primer and patch IMHO specifically made for plastic. So not certain whether it would work for metal, also stripping would be an issue for restoring old builds. Thanks!
