Stickers arrived in the post today. Think the overall effect looks ok and is a close match to the original.
Issue is that the gel coat on the bonnet area/sides is probably the most yellowish in terms of shade of white hence the white gloss vinyl backed stickers with the driver / co driver name script stands out quite a lot against the panel.
I’ve found someone who can do the same size script in black die cut vinyl so there would be no gloss white background and they would be applied straight to the body work (eg like the Shell and Pirelli logos). For sake of £20 which is the cost of a pair of these I think I will go ahead and do the job properly.
The gloss white vinyl background on the sill stickers I had made up doesn’t seem to stand out at all so I guess the sills must be a brighter shade of gelcoat or you don’t notice it so much given they are lower down on the car, shadows etc ???
