polishing valve covers
Looking for some help as to the best and least expensive way for me to polish my aluminum valve covers and if that goes good maybe the intake too. Any help would be appreciated

Re: polishing valve covers
Howard,
This is the parts board. Items for sale. Your question should go in the general forum.

Re: polishing valve covers
NOVAFROG; Thanks for the comeback. I didn't know about the detail forum until this post. After all the different kinds of posts on the parts forum, as Hillary would say, what difference does it make. Besides, how many members check the detail forum often?
I'll try the mag polish. Thanks again Howard |

Re: polishing valve covers
Take some time and search the web for razor buffs. These are small round buffing wheels (3" to 4" in size) that can be used on either an air die grinder or an electric one. With the different polishing material and these buffs, you can polish your valve covers out without working your elbow grease out of the socket. I get my polishing sticks at local truck stops and then use the buffs to do the work.
Oh and by the way Howard, this is the detailing section. Just an observation

Re: polishing valve covers
Are your covers and intake "polished" (smooth finish) already, or are they raw (as cast) aluminum?

Re: polishing valve covers
Thanks Frank and Leddzepp
The Valve covers are already smooth but the intake is not. I'll bead blast the intake and, with your information, polish the valve covers. Thanks for the help guys Howard |

Re: polishing valve covers
You might consider clearing the intake once it's blasted, that way you won't have to polish it.

Re: polishing valve covers
Careful on your choice of clear coat. I have seen many that turn yellow with the application of some engine heat.

Re: polishing valve covers
Those pictures dont do any justice. I have seen the cover he did in person and its spectacular.
I've taken a break on mine since I'm going LS and can't use those covers on the new motor.
