I don't understand the fascination with the sections thing? that's how all detailers do cars is it not? I'll confess to laying off the perfect straight edge 50/50's with tape just lately as I've been wanting to get the job done , but I still use a point of reference on the panel and do it in sections.
That's a great detail though, thanks for sharing it with us Barry. Colour is amazing. You'd think it was black looking at the early evening pics when it was finished, but as soon as there's light on it, there's red fleck everywhere!
