@sss its been ages ( a year maybe) and no signs of excessive wear.
I don’t measure my chain wear but I’m ~500miles in on one chain with UBS and it’s not un-worn (not quite silent, not quite such immediate shifting as when new). It stays nice and clean, but it only lasts <50miles in the clean and dry, and I’m not convinced it’s that great as a lubricant.
I’ll probably use the rest as a wax to protect the frame after washing.
Also it’s a faff to apply, it’t too thin to coat the chain properly so you have to sit there and spin the cranks for minutes until it dries and thickens enough not to drip straight off.
Compared to putoline which I’d not have expected to require re-applying once in this time and probably negligible evidence of wear it’s just not in the same league.
