I'm a little frustrated that, so far, I've not found a shop that can mix interior wall paint to match Porsche paint codes.
Now... I realize the depth of a high-quality, multi-stage automotive paint job can't be reproduced (w/o ridiculous expense, anyway) on a wall, but I'd a thought there'd be SOME correlation to get the basic shade. Anybody have better luck? ideas? I'd like to match Signal Red, but I don't have a pristine sample to try and match even by swatch. Hoping to avoid ordering the automotive touch-up paint for matching.
