Discoloured plenum

[mbw1406]

The plenum and other aluminium parts in the engine bay are kind of crappy looking. Wondering whats the best D.I.Y way to getting them looking better?
Thanks in advance

Brasso is great for bringing the shine back into metal.

Ally tends to get a bit rough when exposed & the oxide coating is quite thick (this is what actually protects the ally from further corrosion.) If the Brasso doesn't work, then I'd go for a piece of scotch brite & then wet & dry paper or a light wire brush with a dremel. I've not tried it but T-cut might be good too, just try it on something unimportant first! The problem with cleaning up Ally is that it becomes addictive & you end up pursuing a better & better finish!

Loz is right, it takes hours. Get yourself a Dremmel and polishing wheel and some brasso or T-cut. When you are finished I would recommend coating it with a heat proof lacquer to preserve the shine.

Alternatively see if anyone is offering stainless steel Plenums or better still a chromed plenum.

(This does sound like a medical condition though!)

or just paint them would be quicker all round

or...
Take 'em to a metal polishers & then get them lacquered as Waynne's suggested.

Ooooooooooo shiny shiny lol

highly polished stuff always looks nice under the bonnet.

i normally just paint mine as its an inexpensive way of transforming the engine bay and adds a bit of colour at the same time,

painted a set of vec v6 plenums in crystal topaz (TVR flip paint) a couple of years ago and they were stunning

Don't lacquer anything polished under the bonnet of a GTO, it WILL tarnish and crack. Trust me.
A polished plenum, and a few other items.

 

[2fast2catch]

now thats stunning

 

[mbw1406]

Man that looks stunning, if I ever manage to get mine looking as well I'll be afraid to start the damn car!!!

 

[saddler]

depending where you are.. i can polish. chrome , powder coat and anodising..

 

[MasterAuron]

Where about in the midlands are you mate? How much to polish a rocker cover about 14" x 4" off the top of my head?
