Thank you all so far – further contributions very welcome! – for your comments and suggestions: I knew Briskoda would be the place to ask. I think that you’ve succeeded in putting me on a much more common sensical path. Everything you’ve all mentioned has been useful, but I’ll pick up on a few points: Paint Protection Film honestly seems OTT in general and both too expensive and not practical for the real world, so I’m going to ditch that thought. If ceramic coating isn’t primarily protective and also ideally needs to be done at delivery, I can’t see the point of that either. As an aside, Skodas are not common here in France and the (relatively few, anyway) dealers are often in the hands of very few businesses. Sadly, my supplying garage is pretty awful in all respects – there wasn’t really a practical alternative - and I wouldn’t trust them not to make a massive mess and charge me a ridiculous amount. Like whippersnapper, travs and others, I think that regular, careful attention to cleaning and bodywork preservation is the only thing that makes sense. Interestingly (to me!), stubev156 mentions ‘something called Diamondbrite.’ Although I am pretty sure it won’t be the same product, this takes me back to ……. A Long Long Time Ago (1980s) and my first car, a Golf Diesel (one of the very first – these were the days when I was given a map of the UK with stations that sold diesel for cars marked on it and people looked, as though it was a tractor, when they heard me coming through the streets of Bournemouth!) I bought something called Liquid Diamond and, after a not very professional wash, simply applied coat after dried coat for about 5 days. It seemed to provide a definite and quite thick patina and, when I sold it many years later, the only significant rust was where a dealer had backed it into a vehicle hoist and bashed in the rear end (thank you John Fox, Basford, Nottingham) With my subsequent cars – all VW and then Skodas – I’ve followed the same regimen, but using Collinite instead. It is insanely dry and dusty here (37 at the moment – midday) and washing is out of the question, which is a pity, because my Yeti (bought in 2011 and which I intend to keep, as I’d get no more than £3,500 for it here) still looks really good. I’m going to read all this in more detail, as there’s a lot I want to follow up, but thanks again very much.
