Anyone know a paint shop that uses House of Kolor paints?

I really like a couple of the Dekerf options, I asked him for the mix instructions/ formula/ whatever so I could get someone in the UK to match it. He told me to find someone who uses the H of K stuff and that they’d have all the same colours.

I’ve emailed a couple I’ve found on t’internet, but they’re all auto specialists and don’t seem to be interested.

Any ideas?

Cheers,
