The numbers measure different things, so hard to compare. One of the biggest sources of variation listed is the weather, while the first paint was done in a workshop (presumably where there is no influence from the weather).
Also, a painting campaign also includes:
> ... a preparatory stage to search for the most corroded areas ... these areas are then stripped, and a first coat of an anti-rust primer is applied
...presumably there was no corrosion just after the parts were originally made.
- stephen_g 3y agoFor sure on corrosion/rust - I’m experiencing this on a very small scale now - I’m working on repainting my old barbecue, it’s incredible how much time it takes to strip, apply rust remover, clean, fill, sand, prime and repaint the metal parts. Easily 5 to 10 times as much effort and time than it would take to paint fresh parts.
