    Literally that...

    Stripped the car...
    Sending the body and panels off to be painted.

    What do you all do with your nuts, bolts and washers?
    I am not keen on painting them as they chip when tightening and touching after will look poor ?

    Have you used black oxide.

    Any advice on what you all do please.

    Some members get them zinc plated which helps stop them from further rusting. Others like myself have stainless steel (but there are discussions regarding electrolysis with this).

    I just replace mine with new as i go, zinc plated for safety critical stuff, stainless pretty much anywhere else. If you can get hold of some JIS ones all the better, but the usual metric stuff is good for most things, except where the smaller heads of the JIS would make using the normal metric, which are quite a bit larger, difficult.
    Like the brake disc to hub bolts for example.

    I would personally try to save as many of them as you can.

    Trust me on this, @Huw recently tried it out too and the results are great.

    Put all your nuts and bolts through a petrol or thinners wash to get the paint and grease off - the grease would prevent the next stage working well.

    Get loads of cheap and nasty lemon juice 6-7 bottles @60p/ea from the supermarket, pour into a bowl or container. Add a table spoon of sea salt and stir. Then pour all the said rusty metal parts into the bowl and leave for 12-20 hours. You will be stunned at how good they come out and how much rust disappears. Beware though, the solution after the soak smells sulphurous and may not be a ideal to inhale it in an unventilated area.

    Once you pull them out, they will need neutralising quickly - rinse well with water and then use the liquid Jenolite or other solution to take care of them and prevent future rusting while they await plating.

    I used a company in Crawley called YB Plating - while not the cheapest, they were great, not silly expensive and offered to keep my items separated and bag them as I had (I bagged and tagged all nuts / bolts etc).

    If you do plate them, make sure you clearcoat things like fuel rails, pulleys, brackets etc as the plating will still go off after some years and lots of moisture.

    So why go through this hassle if sending them off to a plating company anyway? Well, I found that while they dip them in some kind of acid, certain parts didn’t clean up well enough for the plating to look as good as it could have.

    Here is a before and after using the lemon juice / salt solution and an old ice creme tub (I think this was an overnight soak of about 12 hours) ...

    I'll second the re-plating, I don't know where you're based but they're pretty reasonable round our way, you'd be looking at about £80 for all of the nuts and bolts to be re-done.

    Yep think I paid similar, they use a technique called barrel plating to do a bucket full so it’s reasonably priced. You need to have all paint off for it to work. 9CF7BBDA-08F3-4CC1-8ACA-68B7906DE8C5.jpeg

    Depends on how original you want your restoration to go. On any bolts that are visible, and even ones that are not, I would want to get them yellow zinc plated which is the closest to original you can go to. I think they were cadmium plated from the factory but it's not a process that is available easily anymore.

    If you are going down this route prepare for any good platers to have quite a long wait time.

    That looks amazing.

    When you get to fitting these, you are at one of the most satisfying parts of a restoration having it all painted and fitting all the shiny bits on.

    Thanks so much for your responses, I didnt want a shiny new paint job and dirty old bolts.

    The pictures of all of yours re plated is really satisfying :bow:
    Unless anyone can recommend anyone else local to Derby I will search out YB plating.

    Really looking forward to getting to this part of the build... I'm upto my neck in stripping underseal still .....

    To nitpick slightly: None of the plating on these cars was Cadmium. It was Zinc, and either dull finish (EG radiator hose clamps, door strikers, JIS door furniture bolts etc) or with a yellow/'gold' passivated finish.

    Rivet counters love this kind of subject...

    PS: I've used Derby Plating several times in the past but was not happy with my last batch. Too expensive, some parts missing and they chrome plated something that I wanted in gold zinc (scrapping it in the process). I don't use them anymore.

    Thanks for the ps. I will have a look around.
    It would be great to get the bonnet stay etc re coated.
    Now I have seen the excellent work in the pictures.

    Anyone use any of the DIY zinc plating kits on eBay etc? It's what I am wanting to try - eventually!

    I myself was going to try my hand at zinc plating, there's quite a lot of metal parts (not including the nuts and bolts) that could use some rust prevention.

    Reading up on it looks like a simple chemistry set. I like the sound of that cleaning process using chemical bath / electrolysis.

    Colours too. Could do different zinc shades.

    I bought one of these kits. Then I moved. It's one of the boxes we have stacked up somewhere...!
