I have an early plenum, so I can't fit the J30 covers, however I do have access to a 95+ inlet from a chap in Kent..the Z32Inovations covers are not nice. In the meantime however in case I don't go that route, has anyone successfully (without the use of chrome or any other plating), brought these to a more 'fresh' appearance?

 

Currently, they're like this (as with most Z32s).

 

Yes used a brillo wheel first to get rid of the rust then a sisal wheel on a drill with some compound, but you still need to keep on top of cleaning as they will eventually oxidise again as they are steel.

 

I got all the gear if you want to send the linkeage with the clocks when you go away :thumbup1:

Try using brake cleaner and a toothbrush first. I got mine to this stage and kept the anti corrosion finish on the springs.

 

It's not rust, it's the brown coating.

 

Thanks guys. :)

I seriously need to find out how to do this!! That's some fantastic work !!

Lots of youtube vids on how to polish lol, its just so time consuming when doing the plenum, other stuff like water pipes and smaller parts is not so bad, but the hardest part of the whole polishing engine parts job is keeping up with the finish. You have to set aside some time per week/month, to keep the shine.

There are a couple of types of systems to use, the metallic composition to take into consideration, eg steel or ali etc have different make ups in chemical compounds and how these are affected when polishing.

 

Prep is key and the smoother the finish before polishing the better result achieved :thumbup1:

Graham what was the name for that polishing stuff you got hold of at the NEC?

Ive tried a small dremmel grinding stone on the top of my plenum!

No way is it that good!

What tool attachments were they?

Dremel is only good for nooks and crannies, originally i bought a whole set of sisal and buffing wheels to mount on a drill, the speed needs to be fairly high, then exert some pressure, the dremel isnt strong enough when you put too much pressure.

 

I will start another thread lol on how i did mine and the new system i bought at the NEC to stop clogging Si's thread further :thumbup1:

These are mine

 

 

Just cleaned in petrol
