This is the TPI intake plenum I just polished for my buddy. Looks pretty good, he was originally going to go with a satin finish but I wasn't going to allow that.

Plenum looks quite nice

Plenum looks purty.

what did you use? sand it first? rouge polish? dremel, die grinder? how long did that take you?

heres mine...

Well I work for a wheel refinishing shop, and we also do polishing... Which I am slowly moving into. The polishing division that is.

Basically I palm sanded it from 180 - 400 and then hit it with the buff. It took me about 45 minutes with these tools.

so say if i was doing it by hand what would i need.

you got any pics of what it looked like before?

Like a stock VERY dirty manifold.

I don't know how you'd polish that by hand man, it would take FOREVER.

im actually attempting to polish my tpi setup also, i got the plenum to look just as good as that and i still need some wetsanding and actual polish. Got instructions from the main page on this site . i got the plenum to 600 and im working on the runners now. those arent going to come out as nice as the plenum though.
