Maybe it had been damaged from a stone chip. Keep going round and every wheel is fucked. Multiple spots with bubbling

I had it refurbed 2.5 years ago by Lepsons so it’s no longer covered by warranty and it’s only done 9000 miles since then and always parked in a garage/under cover so I think it’s frankly piss poor and wasn’t prepped correctly.
I’m not sure if I’ll bother going back to them, best case scenario I get offered a discount but I’m not sure it’s worth it it if I get the same result as it’s frankly the standard that I’d expect from a rushed smart repair for £30 a wheel…
