Powdercoating TB, intake and fuel rails?
 

I know the intake can be powdercoated, but would it be ok to powdercoat the TB and blades, and fuel rail?

I don't know why you would paint the blades, you will never see them.

Same reason Holley TB blades are red. You never see them. It just looks cool. Besides it shouldn't cost much at all to powdercoat them. I just want to know if anyone has done it or if it would be bad.

A cheaper way is to get a hi-temp rattle can (engine paint). I did this on my stock throttle body and it came out b-e-a-utiful. Just make sure you do it right(block all passages) remove from car etc. and most importantly at the appropriate distance.

It has never faded and almost looks like it was professionally powdercoated...

You can even take it a step further and have the alternator, water pump, and accessory bracket powder coated as well.
