1. Don't know, but the acetic acid business dissipates after the cure. Having said that, the 'proper' potting compounds make quite an issue about the curing process as there are a number of issues. Have a Google.
2. Don't know. Many durable cables use modified PVC and PTFE (and probably all sorts of wierd plastics) for outside use (damp, UV, temperature, schoolboys etc.)
So, have another Google. I don't think there is a one-size-fits-all answer.
I really don't know how non-stick is stuck. I'm sur someone can Google and pretend they knew all along. Now where is he?
My best frying pan before SKK was a made in France tefal, which finally failed after 10 years.
We had a couple of expensive stainless Meyers, both failed after about a year, non-sick very soft and eventually blistered. However, a Meyer Analon Pro (anodised al then coated) is proving to be very good too. Did some scrambled eggs this mroning, overcooked of course, and washing was no problem. Ten seconds with a cloth and Fairy Liquid. All a bit pricey though.
