well now that sounds as though I would may be a person with no technical knowledge, however you miss my point, if I wanted to restore a full trim then I would probably use what is known as common sense and maybe use a proprietary brand of paint or for something as trivial as a sun visor just spray something on and see how it goes, if it was rare then get a sunvisor covered in vinyl from a scrapyard and try it on that,if you have read my posts you would realise that I do share technical knowledge when I feel it may be relevant but know my shortcomings and 36 years in mechanical engineering with a stint running my own business in fabrication is probably nothing to draw upon in any case, however 54 years as a born and bred Yorkshireman does tend to make me have a slightly dry sense of humour and reall what is the worst that could happen to your sun visors? keep me informed please100% relevant to someone rebuilding a car. If its so boring why not post a few technical threads yourself? Really don't understand the need for comments like that on a site where we're all supposed to have a common interest. Colouring & restoring trim is about as relevant as it gets whether its a sunvisor or a headlining.
