Coating injectors ?

[stewardc]

I think it's time to do some blingage under the hood and clean this thing up some. I'm going to have the injector hardlines chromed, but had anyone ever coated/chromed the actual injector bodies? I'm thinking either chronme or powdercoating. Got any ideas?

I've seen folks polish the injectors to a mirror finish, but chrome?  My only worry is the injection pulses would eventually break down the coating through many many vibration cycles.  I think either mirror polishing or powdercoating would be better, as a polymer powder coat would be cured under heat to allow it to flow and form a "skin" so it would stand up to vibration better.  
Hmmmm . . . chrome powdercoat?

Yes, you can polish the ssteel, but it just rusts faster. I've actually been looking into chrome powdercoat. I had a G60 cover finished i that on the old 1.6 TD. It was very nice.

Bump...

How would you get the powder coated injectors in without damaging the finish.  One 27mm socket and the torque needed to get the heat shield tight and you would mess em up would you not? 

Wrap with duct tape and use a 30MM? 

Just wondering.  But I like blink as much as the next guy.  Try it and let us know.  Thanks

Thin Mylar sheet, cut & wrapped around the inside of a socket has worked well for me in the past. I have never scarred any hex fitting/hardware using this tecnique.

I've gotten away with taking off finished and painted fasteners by taking the next size up of a socket (i.e. 28mm for a 27mm fastener) and wrapping the inside with some electrical tape.  I will admit, though, that those fasteners weren't to the same torque value an injector would be.  I think a mylar sheet like shorttimer suggests would be the best way, either that or a hard plastic socket like some folks use on their wheel bolts so they don't mar their anodized wheels.  It's very picky stuff, this coating preservation business.

Overall I like the idea of Chrome PCing them.  Hopefully the hardness of the chrome and the flexibility of the powder coating can take the torque of the socket tightening them down as well as the injection pulses.
