I was wondering if anyone has seen any good write ups on how to polish and intake mani & valve cover. Or if you have done this before would you mind giving me step by step directions along with a material list. This will most likely be my next little project. And all help will be apprecaited.

Thanks,
Justin

 

i would say start off with a 350 grit and sand it down then work your way up, 400 800 1000 2000 3000, then use some nice metal polishing compound,

btw i am no expert, so this is just what i have heard....it would be similar to polsihing wheels, so if u can find a write up on that, you can apply it to this..

 

mine:



i would start with somthing with a bit more grit. something like 80 to get it flat. them work your way up from there. mine had some divits the were impossible to get out..

 

Ok so basically sand it till its flat then move up in grit. Then polish it with metal polish. Is there any polishes you would recommend?

 

All the info you need.... VWvortex Forums: ***How to Polish***

 

Awesome!!! Thats what i was looking for. But one more question. In the write up it mentioned wet sanding. Well is this necessary?

 

Wet sanding is a must when it comes to polishing .With wet sanding from 300 to 1200. (or if you want to take it even lighter) With dry sanding at those grits your sand paper will hold the dust from the manifold in the paper, and cause heavier scratching then the grit of the sandpaper.
So when you use wetsanding paper and water, the build up in your paper will turn to a liquid, which won't cause scratching, you will see more of the mirror image your looking for.
Use a Dremel and start with an 80 or 120grit sanding drum to strip down the texture on the maniflod first, then start with a 120 dry paper. Then work with 220dry, and then go with 320 wet, and work your way up.
That's the way I've done quite a bit of my own parts in the past.

 

Most important part of the process

 

yea, it takes so long, but im gonna have to do it when i get the a8's

 

i wanna polish mine too... since they are the only thing that sticks out past the engine cover... and 2.0's are ugly as sin without the cover.
