I have a small tippex style bottle, 12ml, of the genuine Hymer paint for my dimpled 2017 Triton. The Hymer code is 1887165. I do not know what the RAL code is, but Hymer call it "Carrarra Weib"
After collecting my the van new from Lowdhams of Nottingham I got home to discover small marks on the front. They had been touched in poorly and I was not happy. I told Lowdhams I expected a genuine touch-up paint and they provided one. When first applied the coolur is a good match, but after a couple of months the paint colour has changed. As a result I re-touch in the areas a couple of times a year.
