Spare tire rim question

[SurferD]

You must coat the bare metal with something at least until you sort the correct colors. After blast and before paint you should do a phosphate wash to prevent corrosion. Eastwood makes a good one but you have to be careful to wipe as directed because it pools and leaves hard deposits. Not bad unless it’s the outside surface.
