When my job included specifying zinc plated hardware and brackets etc in the 1970s into the 1980s, clear passivation was achieved commercially by passivating yellow followed by bleaching to clear (silver).
Yellow passivation was - and I expect still is - much more durable than clear passivation, achieving about three times the hours to corrosion in accelerated salt-spray tests.
For those unfamiliar with the technology, the zinc protects the substrate and the passivation protects the zinc.

Here are some of the items I have plated with the home kit. The problem encountered with the yellow sacrificial coating has been the adhesion. However since I have left the items over a long period of time the coating has hardened. So I think the 24hr period suggested until it can be placed in a mechanical situation is a little underestimated. I like the idea you can strip down small assemblies plate them and put them back together quickly. However you if take boxes and boxes of parts to the plater you get value for money over small batch quantities.

Good to meet you at the weekend in Lincolnshire! Amazing quality of work as usual, HOWEVER I personally do not like the red trailing arms!!!
Mine are all just covered in mud anyway, so could be any colour1

The trim code will have a 'C' in it if the interior had the cloth faced seats. Personally I like the grey vinyl and have that in my Mallard blue PI. It was originally black inside! All down to an individuals taste. Most things are reversible anyway!
I would go for the OD box if the car is to be driven a lot. If just a show car then it doesn't matter quite so much. My rally car had no OD when I got it, and I think the 'box was rebuilt, but has not been used. Just sitting it the workshop. All up to you in the end.
