Taking inspiration from post #101 from Under hood pictures please post!, I decided to polish my A/C lines today. Used some fine grit sandpaper in a few spots followed by some polishing compound with a microfiber, and now I'm sitting here wondering how I couldn't have thought of this myself? I've got more work to do, but so far I'm really happy with the result.

Even before the polishing, I've never been happy with the big grey cap on the A/C line. I've got plenty of Billet Technology pieces in my engine bay, but never could quite pull the trigger on the A/C cap. Well with the newly polished lines, I had to do something about it so I decided to see if the plastic would take dye and I'm happy to report that it did! Now the plastic caps are a perfectly homogeneous dark black, and a much better fit with the rest of the engine compartment.

Very nice. Mostly free mod that makes such a difference. I may have to add that to my list. The V6 at least has a big tube on the left side that may polish up as well

The tube to the left is polished as well?

Yes I did polish the left/lower tube too, but its a bit coarser so it isn't as shiny as the smaller tube. I'm going to work on it with progressively finer sandpaper until I can get a mirror-like finish. I also polished the lines behind the engine visible in this attached photo, but they're funny as they have rough and smooth areas, so the finish isn't perfect. I'll be working on them too.

Dying the AC cap is a great idea. I have dyed a lot of RC car plastic pieces and never thought of doing that. Looks great. Will have to try that. I wonder if the dipstick handle would take dye.

That all came out nice. Personally, I wouldn't do stuff like that, underhood is more about performance and functionality to me. But, I like stuff like that a lot more than changing colors, billet stuff just for appearance, stuff like that.
Dyeing the caps was a good idea, and they look more "Factory" than when new.

Thanks! That's exactly where I got the idea, as I dyed a lot of the parts on my RC cars years ago to get the color schemes I wanted. I will go ahead and let you know that I already tried dying the yellow windshield washer fluid cap about a year ago and that plastic would not take the dye. It looks like the washer fluid cap is the same plastic as the oil dipstick handle so I have a feeling it won't work, but if you try and find success please let me know!

Try steel wool on your AC lines. Might be easier to work with than sandpaper. Not as aggressive. Flitz polish works pretty good on shining things up also. I use it on the motorcycle.

The AC lines look great 'PrestonRT .
Excellent idea,
Best regards

Right on, I hear you about the performance, but why not look good while your winning too? Best of both worlds!

Thanks for the advice! I will try the steel wool after work tonight.

Actually now that I think about it, I suppose you could find yourself in this situation.

I had a feeling the dip stick might not take dye being it is a harder type plastic.

I too have dyed RC parts in the past. RC10T stuff IIRC. Other "mods" I have seen under the hood, that I like, are people painting/coating the factory coolant reservoir black or bedliner stuff. So it is still looking factory, just not that odd milky colored look that is never attractive.
I wish I had a picture of my father in laws old 1998 Subaru Impresa RS. It had the ugliest underhood I have ever seen, everything, EVERYTHING was basically the color of cardboard. Chrome fuel rail, hoses, belts, engine... It had (I think) 230K miles, and was all original other then fluid/filters. Still had the original clutch. He drove about 120miles a day for a few years and really racked up the miles on it. I would have been as proud of that as one that was detailed.

I had polished the door catch on my car (mounted on door jamb body). Looks like it is plated with some kind of galvanizing or nickel? Polish came out nice. However now rust has popped up. I had some wax on it, but apparently didn't do a good enough job.
Hopefully polishing the line doesn't remove some kind of protection?

The door catch, wow that's a great idea! And the fact that they are easily removable will allow me to polish them inside which will make it much easier. I'll look into whether there is a coating on it first though.

Thanks!

They polished nice, not sure how to keep them blemish free.
I did buy a stainless steel hood latch. That polished up nice and has stayed that way.

Here is the door latch after and before polishing.

Maybe I can try to polish off the rust spots, and then clear coat or seal somehow.

I used a bench wheel buffer to remove the easily accessed surfaces. Then I used a JoolTool and flex shaft to get the remaining inside areas.
