Thanks!
The
problem is that they do not claim it will last for two years, its always 'up to', so you can't take it to court. They also do not claim it protects the car from something, its always a word game. Its not about the type of product, all ceramic coatings have similar hardness, take a similar time to cure (Sonax says 3 hours on the packaging, but on their educations for detailers they say 12 hours). Sonax trainer said to me it could last two years but expect a year if you are not really into detailing and protecting your car. Every time you pressure wash your car with chemicals you take some of it off. And if there is a speckle of dust embedded within it will become a weak point the coating will come off easier at that point. Its not rocket science of course and its not like its will come off after a month, but it shortens the coating life significantly. I understand the cost savings, but then just dont do the ceramics but invest in a good polymer coat that you can apply yourself once in 6 months and other detailing supplies, you can get all you need for 2 years of washes and protection for 400 quid, even the pressure washer.
I paid a miniscule sum because he is my friend, I got it for 150 euros

He usually charges under 400 euros for full detail, polish and coating, but we do live in Bosnia where labour and everything is around 3 times cheaper than in UK, and we also have way lower crime rates, extremely beatiful landscappes, hotter chicks and cheap beer (free commercial).
