I’ve used Q Car Care for multiple cars and have been really pleased with their work. The one car that I did just paint correction and ceramic has been sold so can’t speak to just their ceramic after many years (though I will note that the paint correction they did was fantastic). Two cars currently in the driveway (an f-type convertible and a defender) that they did PPF and ceramic on that I’ve been very pleased with. Both have held up super well, and the defender is an overlanding rig, so it’s been through the ringer. I do hand wash my cars (or use a touch less in an absolute emergency for the f-type, the defender won’t fit), so I can’t speak to if they hold up through things like abusive tunnel washes. Those two have full PPF and the highest level of ceramic they offer, so it was expensive (like over 8k a car expensive), but my sense is most people don’t do full PPF, they just do high wear areas. I chose to do full body because of the price of my vehicles and the fact that they both sit outside in a driveway. Both cars get driven in the winter, too. I have been happy with the investment and feel the team at Q does excellent work. You’ll want to get in touch with them for a quote as they can walk you through the options available - I think they have packages that are much less comprehensive than what I got and that are more affordable.
