[Al (astral highway)]

hey Mark,

Thank you, that's very kind of you. In the end, I've decided to try an alternative technique - several turns of silicon sleeving, secured with lashings of epoxy resin, and then over-painted with my new test solution of transformer oil and turpentine. (There's another thread about this). The transformer oil should be left behind as a thin residue that can be overpainted with gloss (marine, oil-based) varnish.

I really appreciate your offer and if there are other bits of circular fettling that are beyond me, perhaps I could ask you in future?

Thanks again!
