Chuck, I was a big Alclad fanboy, because for that many years they were simply the very best that those of us with 'shallow pockets' could buy to get the elusive NMF finish that didn't look like silver paint.
I was encouraged to try AK Xreme Metals by a mate who said he'd tried and thought they were every bit as good AND (more importantly) easily available here in NZ.
So I tried and they're every bit as good as Alclads' but more (far more) resilient to handling. I still have the Alclads I brought out with me but never bothered to replace or renew. The half-dozen AK's that I use regularly, I've renewed twice.
Ian.
