porsche fan, polished or painted, what do you prefer?

Its a good idea it should look really good.
But, I mean when a porsche fan is used it looks good anyway so its just up to everyones taste, as long as what you do does not harm the fans "performances".

I like Jakes suggestion regarding the clear powder-coating. As fo myself, I painted my fan with a high-temp silver automotive engine paint and followed it up with a automotive engine clear coat. It looks stock and like a freshly casted part. The silver tends to rub off and that is why I clear coated it. I have two powdercoated ring/alt-shrouds and two plain shrouds. I usually try to go with the "factory" look but sometimes you have to go with the engine bay theme. I usually have the pulley and straps painted or anodized. You can also go with stainless straps. I also sometimes glass-bead blast the aluminum, magnesium, or Al-Mag parts. The resulting finish is somewhat factory. One positive thing about this last option is that bead-blasting sometimes "may" slightly (very slightly, if any) peen the surface and thus reducing the tendency of micro-fractures from propagating into larger cracks. Bead-blasting will remove any surface oxidation or films that are hiding some bad surface corrosion actions. After you bead-blast, protect with a clear coat. Polishing is great but "a pain in the you know what" to achieve and maintain. Polishing also may, to a greater extent, reduce surface micro-fractures that may develop under certain conditions. I make my own Type 1 fiberglass shrouds and relative mounting parts out of Aluminum-Magnesium. Anyhow, Good luck!! Make sure you do all you can "to minimize" overcooling and fan choking. You have to make the engine compatible to the fan setup's capacities. If you dont, you'll hate your setup :doh: and be disappointed !!! Check different forums and look at my and other's suggestions regarding what you can do to make the setup work as best as possible.

I have just experimented with having our powder coater do a candy apple blue over a polished fan...IT LOOKS AWESOME, almost like it is anodized....
