I have some of those, no problems with the finish as yet. But I'm a fair weather biker these days Postage is a bit steep at 24 quid though, making each bolt about 10 quid Ah bugger, post is free in the UK Surprisingly if you buy 50 of the 50mm m8 ones it's £34 posted over here so only 68p each posted ☹️ It would be way cheaper me buying some and posting to Jon Steve

Thanks Steve, the offer is very kind but I reckon my long suffering mum might be able to sort for me as she has some other parts to send me at some point in the future, but the thought is very much appreciated.

I have a zinc/nickel plating kit with clear/blue, yellow and olive drab passivate. The clear blue is coming out great at the moment but the olive drab has been a bit pale but I've not done more than two or three items this time around. I wondered if a bought, or rather obtained from work, clear/blue passivated set screw could be passivated olive so I tried some. Normally 30 seconds is around the immersion time needed for the passivate but I tried anything up to 3 or 4 minutes and all I could get was a pale green but it it was similar to one I had plated myself. When I get back to it I'll try maybe a quick dip in the dry acid salts before passivating and see how that does. My idea is the acid might allow the passivate to take hold better but it's just speculation. If something has been clear passivated the olive won't go over it as the surface is sealed At times I've had a batch done in clear then picked out the bits I want olive You need to acid dip them for a few seconds just till they start to fizz then dunk in fresh water to rinse then straight into the olive That will sort it out. You can get darkener for the olive. I used it when I first made my batch up as it was quite khaki in colour. You just add a drop at a time and test with some spare zinc plated bolts Got black too 😁 Steve It did actually work on screws from work, just not very dark. To be honest though the ones I did from scratch weren't much, if any, darker. On the other hand the passivate is about 15 years old. I have some new stuff to try when I get around to it. I'll try the dunking bit, thanks.
