does anyone have any how-to's on polishing. valvecover, intake manifold, anything. i jus need the process to get the idea. o and i searched and didnt find anything usefull.

 

I did my valve cover.
Stripped paint with brake cleaner, sanded literally until I blistered with 320 wet/dry paper, then again with 1000, then polished with dremel and then by hand to finish. There are lots of little pin holes in the metal of the valve cover so you have to sand those out before you can begin to polish. I'll send you an email with pics. It would be easiest to chrome the intake mani.

 

The paint came off easily with brake cleaner?

I've been wanting to repaint my valvecover with that crinkle red paint made by VHT or whatever it is. I have off this weekend so thats probably gonna be my project

 

well i searched the web and found some good info. but damn everyone says to use a diffrent kind of polish. i guess polish is polish. but it has to be aluminum polish correct?

 

Na just metal polish. I've used Mothers and Blue Magic and I prefer the latter of the two. There are more out there, you have to find YOUR brand

 

Sand, sand, sand.....then sand some more. You won't have any fingerprints left on your fingers if you do it properly. Use lots of water, the highest grit sandpaper you can find for the last sanding. I used Nev R Dull(sp) for the final polish and it worked well. I guess this has been covered, just thought I'd throw in my experience.

 

I bought a polisher, It looks like a bench grinder, but the good ones have longer arms, for ease of access, buy some metal polish, I think rouge is what used, but everyone is right you have to sand first, the more the better, to get out the imperfections from the casting, prepare to get black from the aluminum, very messy job. Once your happy with the finish, think about clear coating it, to help it stay nice looking, because if anyone even touches it while it's warm/hot there will be a permanent fingerprint there from the oil on there hands, and you'll have to do it all over again, it's not a fun job, the better the polisher (rpm/tourqe) the faster easier it will be, but a high quality polisher can cost well over $200.00, but then you'll have it forever and can polish almost anything
