Quick update, all going well. The powder coat colour is great, but the powder coat lacquer definitely not as robust. I got the lacquer from a different supplier, so I suspect it is a different type of powder coat. E.g. one is epoxy and the other polyester, or whatever.
I fitted the suspension rubber rear frame clip. This is so much better when wheeling it about unfolded.
I'll probably not be posting for a while, but I'll keep this thread updated in case anything changes.
