I was only one "o" wrong in my thinking, not THAT much to be called dirty old swine eh ?? Was I aware this kind of things was/is still in use in the UK ?? Anyway, glad this is all cleared out now, poo belongs in the po, but why not go todeloo ??
This linseed oil sounds cheaper and just as good as the autoglym bumper restorer that I used on my old Previa. That cost about £6 for a bottle, and worked very well also (lint-free cloth required too).
I will get some when the valet wears off in a few weeks!
