Kitchenaid does not make a stainless steel paddle for the Professional 5 lift bowl model, even though they know their coated paddles all eventually start chipping, mine has been bubbling almost since I got it. I’ve seen several requests for it just in this Q&A, not sure why this particular size appears to be the only size you don’t make in stainless steel. But if the ratings are as bad as they appear to be, maybe I’m better off without it.
