Peek is indeed good stuff and the best I've tried for getting a chrome-like final mirror finish on both aluminium and stainless but it's getting increasingly difficult if not impossible to find in the shops as it's not apparently been a big seller. Maybe the name is a bit uninspiring. I had a small amount left in the rolled up remains of a tube and have been using it to get the final finish on stainless and titanium fastenings. I can't find any more in the shops, so I've ordered some online. If any of you want some, I suggest you do the same because it may not be available much longer. In fact, I think I'll order a tub and can as well as the 100g tube - just in case...
