Delving into things I have found obtaining a paint formula much more complicated than expected, and it might be simplest just to get a spectral analysis done of an existing painted panel. Here in New Zealand our automotive paints industry is dominated by PPG’s Deltron paint brand. PPG’s Nexa Autocolor paint, which is widely used in the UK, is not available here. The two paints have different chemistries entirely and even the PPG head office for the Pacific region is unable to find a formula conversion for me. However I do have the formula and brand code for Nexa Autocolor in Mountain Blue (NRG1B). It is just no use to me!
My current approach is to try and find another Mountain Blue SP250 in New Zealand or Australia to see what they have used, and maybe persuade them to have their paintwork analyzed for me by a PPG supplier.
