I've got a 2.93 LSD ready to be fitted to my project but I want it looking a lot better. It's currently rusty brown with bits flaking off.

What's the best way to get it looking better, nice and shiny?

Tried a search but nothing really came up.

TIA

You'd be looking at wire-brush, sand, paint for a nice new finish. Be bloody careful masking it up though! I'd pass if it was me...

Why's that? :?

I've read about sand-blasting it?

If you sand blast it might aswell get it powder coated at the same time.

Will sand-blasting it be ok? Don't want to damage anything.

How much would powder coating it cost?

Sandblasting would do a good job. But if it's not stripped down and washed out. then sand will get inside somewhere and then cause damage.

I gave mine a damm good wirebrushing and a couple of coats of Hammerite. Looks fine. :)

Imy, I'm going to use some alismart acid (very small amount) mask off a few bits I don't want it to touch and plenty of wire brush action.

I'm doing the same on the M50 block.

Both will then get a coat of enamel/paint

I wouldn't risk sand blasting it myself, that stuff gets everywhere mate....
How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Interesting interpretation of an overhaul.

Sand-blasting's a no go then, don't want to damage this as it's a pretty rare ratio.

I'll go with wirebrushing.

Thanks for the info lads :cool:

an overhaul id consider cosmetic and a general minor repairs, a rebuild would be more mechanical.

That's how I interpreted it as well.
