bloody hell
look - where not trying to slam you at all, but if you want to get an issue resolved, go in with the item(s) in question and see them personally
it always works better that way
go in with one or two of the rims - or all if you want
explain the story how you wanted them powdercoated - and thats what got done
say that when you got to get tyres on em, the tyre place said that it looked like they had been spray-painted
ask him how powder coating is exactly done and show him the rims and ask him if it looks like its been spray-painted or powder coated
my bet is that they powder coated it, but just the face - cause really, who is going to look INSIDE the rim anyway??? (only the tyre guys will)
