Default Polishing Plenum & Runners.

So i want to polish the plenum and the intake runners on my L98. Years back when i first had the vette i polished the distributor cover and the bracket between the smog pump and the alternator. I did these by hand and they were a real PITA. Eventually all of these are going to be powder coated. So i guess i have alot of questions.

1. Whats the best method when doing this by hand?
2. What grit should I start with and work up to?
3. How can i have it professionally done? Cost?
4. If i powedercoat as is, will the finish look grainy or smooth?

If you guys have any pics of polished and powdercoated plenum and runners i would like to see them. (give me a good idea of what to expect and serve as a swift kick to the butt to get me started)
Thanks

Contact CentralCoaster, he has a fine example of this procedure on his website as well.

Here's mine before and after



I used several grades of sand paper, on an air file then jewelers rouge on a wheel.



The valve covers came out beautiful but they will tanish almost over night. I need to find a way to seal them.

this has worked for me, if you don't touch them with your, by now, very greasy hands, gloves-cotton, and coat them with a good car wax, then buff, they will last quite a while before they start to tarnish, or you can buy the expensive zoop sealer and never have to do it again.

I outsourced the job. Way too much time and effort consumed doing it yourself in my opinion. And you won't get it as shinny a pro would.

These were taken in the shade. I use Mothers aluminum polish with a microfiber cloth to upkeep the shine.

Those do look nice! When i get them polished I will most likely powdercoat 'em white or clear, so im not too concerned with tarnish. Man I am about ready to go home sick and tear into that engine. These pics look reeeeal slick!
