Is this overkill.... I have somewhere that will blast and powder coat the wishbones, but also looked for somewhere local that can hot zinc spray as well. Found somewhere, but they don't powder coat, but they do the following on road sweeper chassis!! Gritblast Zinc metal spray Apply epoxy sealer Apply epoxy zinc phosphate primer Apply two pack gloss finish Colour TBC This is about £400. Is that over kill for the wishbone refurb? Mine are very grotty at the moment, so wanted something that would bring them back up to scratch!

I'm not sure if you can go overkill with these things if the car has a lot of life left. What worries me is whether or not it's worth protecting a wishbone that is already thin from years of rust?

You worry too much😄😄

When people say that you know there is something to actually worry about

Well, in that case, you definitely worry far, far too much 😄😄😄

[gaffer1986]

Haha, well I use the word worry in this instance but on the contrary I'm actually not much of a worrier at all when it comes to material objects. But I think it's a fair comment that people may want to consider before they spend money on something that is potentially scrap? Would be interesting to know the thickness of these tubes new and the minimum thickness required for safe use.

looks like a similar website... one for a fast and agile land vehicle, the other for a slow and clumsy water vehicle. http://www.canalworl...showtopic=68459 Anyway.... no doubt they are not experts, but I have heard this ratio used before 1mm rust, = 0.1mm metal lost.

[gaffer1986]

That's interesting, I really know nothing about rust other than it needs oxygen and water and that unlike other metals, iron oxide does not protect the metal below so rust will continue to get deeper until rusted through. Not sure what they mean about the equation because rust is just a mixture of iron/steel and oxygen so I would expect there to be nearly no metal loss, all elements and compounds are mainly empty space so that explains why it doesn't necessarily expand when oxygen bonds with the iron. It's more the fact that rust is weaker than mild steel. How much weaker is maybe the question I should Google.

It seems to be an "how long is a piece of string question because it all depends how rusty it is.

Ha ha pisser, your like a pair of old women 😂 love it 👍

My tips

 

1. Buy this:

https://www.machinem...oint-separator/

It will save you a heap of time splitting the ball joints

 

2. Get some proper marine grade grease if you go for any of the fancier bushes. I did and never had a problem. Ertacetal bushes felt wonderful on my car. Ask anyone who's driven it. Quite bored of seeing people not recommend them for road use even though they've never tried them....

 

3. Don't grease the threads on bolts.

 

4. It will take time. No matter your ambition it will take longer than you think and you will not enjoy it. Accept it or get someone else to do it.

 

5. It's worth it.

Rust is seven times the volume of steel. Despite the theories other metal oxides aren't all that protective either! The trick with corrosion is to measure the depth of loss.

How do you measure the depth?

Sonething like this for the grease?

How do I measure the length?

[mbes2]

Wouldn't worry.. as the glue will fail before rust gets it

There's a special tool for measuring depth of pits.

[gaffer1986]

I'll Google

[FLD]

It's an aircraft tool used to measure pits in alloy. It's a bit ott for suspension parts.

[Mat Jackson]

It's not generally material loss that will get you with wishbones - you will have to have severe rust issues before this became a problem. What is likely to happen first is local corrosion failure on welds which may lead to cracks, known as stress corrosion cracking. Again, it's not something I'd be too worried about on wishbones.
