Very valid points. Each job Will undoubtedly have a lot of variables price wise.
Was only looking for ball park figures.... somewhere between £200 & £1500 sounds likely
I’d say to do a decent prep (To get good visual end appearance, best adhesion of Ceramic and therefore longevity of product) is £400 minimum from my talking to 3 local guys.
More prep, base layers, wheels done etc adds to that of course.
Oh and yours; in lovely Albi would look AWESOME with Ceramic IMO.
Good luck !
