5 years ago I had all 4 wheels stripped and powder coated. I was well pleased with the result.

The last time I had the wheels off, I noticed a couple of "scabby" patches on the inside of the rims. The advice I seek is what primer should I use when I have sanded the corrosion back to bare metal.

Is there a good primer that is specifically used on bare (after sanding) alloy?

Any advice welcomed,

Thanks............................................ .IP
