Yep you just used the wrong ones. It all comes down to the quality of the tradesman. A crap tradesman in an expensive shed will do a crap job. A skilled tradesman in a van will do a great job. Just swap the words around for the various combo’s. The paint is the same either way. Literally identical. Both use the same scanning device to match the paint. I went off the crash repairers when I called in to see how my 3 week old bmw repair was going at the official bmw approved repairer, to find the windows down and the interior covered in paint dust, and was told it will be fine, they clean it all up. So yeah, each to their own.
