How to spruce up the fan blade?

Is steel wool a good way to get the fan blade shiny again? 63 Spyder.

I don't think the fan blades were ever "shiny". If the fan is off the engine, sandblasting and painting with gloss paint or powdercoat is probably the best was to "spruce up" the fan.

This. Fans were never shiny. An early steel fan I suppose could be plated if shiny was desired. Not sure now the later cast fans would take to that treatment however.

I degrease my LM magnesium fans with mineral spirits, clean again with Simple Green and water, then a plain water rinse. After drying, I bead blast (#13 extra fine glass beads), air blow to remove particles, then paint with VHT High Temp Aluminum paint. They good under a black or dark gray fan shroud.

NOPE - bare magnesium will oxidize to a brown color in short order and corrode. They were coated with a very durable finish that varies from light gray to dark blue gray on the ones I've seen.

If you take a mag fan down to the bare metal then prime and paint. Go online for details.
