I've emailled them to ask about postage to the UK, and will give it a go if its reasonable. I tried the Langka kit, but was unhappy with the colour match of the Halfrauds paint a mate made up for me. If this is a reasonable price, it will hopefully do a better job
It says on the website to use shipping option 3 to post to the UK
missed that
GM colour code is WV2 btw. On this point, I was told by Chips Away there are at least 2 variants of it on their database, so it will be interesting to see what they come up with. Chips Away colour was much lighter than Halfords, but at certain angles the Halfords stuff was just too dark, whereas Chips was a much better match, albeit slightly lighter than OEM.
OK got an email back from them and they do indeed post to the UK with option 3. Think I will order some after pay day (next Monday) and see what happens
