Oddos Raleigh Ronniewagon, Brexit Crust Wanker Hybrid, Gravel Bieks and anodized aluminum

The Fairlight still sits dry in the living room. After a comment on here somewhere from @bur70n_ about using ceramic coating on his new Stayer OG+ I got curious.
I bought some of that unicorn piss in a bottle (£45 and it's tiny) from wax is dead.
The idea is that it makes your frame hydrophobic so that mud doesn't stick to it that much and apparently it also prevents some light scratches.
After putting it on it needs to cure for at least 24hrs so I was pushing that until I had enough time and decent weather.
It's all coated now and put back together and damn that coating is slick. You can really feel it. I tried to put on some clear frame protection stickers but nothing sticks to it anymore :D.

I am hoping to give the bike a first spin on the weekend. There are some issues I need to sort though.

1. Indexing the gears
   
2. My brake adapter doesn't work on this frame so I'll have to use a trp Spyre from the parts box in the front for now
   
3. I am completely overthinking the bar tape choice and nothing I want is available. I got some quality rewrapple black tape I can apply in the meantime
   
4. Finally I need to find out the correct bb spacer combination for Hope BSA 30 bb and the Easton EA90 cranks. This is a bit of a mystery to me. According to this chart from Hope I should use 2 x 1mm spacer for Road cranks (91mm over bearing width) and 2 x 2.5mm for MTB cranks (96.5mm over bearing width). I tried both and Road is too loose and MTB seems a bit tight. Then I found this for cinch cranks which state 92.6 +- 1mm. So should I use 1 x 1mm + 1 x 2.5mm spacer? Which one would go on the drive side?
