I have been battling with RAL codes for the last few months on a completely unrelated project. And trying to get the correct colour and sheen for my Sud alloys, Sprint steel rims and Alfasud steel rims. All different colours of grey.
On steel wheels, it is likely powder coating will not get into the deeper recesses of a steel rim. So they can rust. Etch primed and paint, as they were originally, is where I am going. Except for the alloys. Most steel wheels are now painted bright silver but originally they are more of a grey.
However, you may well have resolved tw
o issues for me and one has to do with the other project and also the choice of finish from the alloys.
So many thanks.
