Having spent some time looking for a Midlands detailer, I finally settled on Dan Stronge of DS Auto Detailing via this site.
After a couple of really helpful email conversations last week, he arrived at 7:45am this morning to set up his 3x6m enclosure on the drive (good job, because predictably it rained all morning).
After 10 hours of washing, claying, machine polishing and finally a coat of GTechniq EXO, it looks like this.
Really, really pleased with the results, and Dan was great at giving me hints and tips as the day went on.
Highly recommended - cheers Dan!
