And one more thing. Here's a website, which I've purchased product from, which in my opinion, updates the aluminum care section to a certain extent. Perfect Polish sells a product called Nuvite which to the best of my knowledge (very limited at best) is a better polish than anything else on the market, assuming you have polished areas on a Kirkham or if someone puchases a completely polished Kirkham.
