IHMO, nothing, I say NOTHING will give you the durability of Glasurit paint (made by BASF). Glasurit is Mercedes factory paint. They have been known to use Spies-Hecker (which is now owned by DuPont, I think), but that was mainly back in the '60s and '70s. I'd say find a shop who uses Glasurit. You will be happiest with the results (that is, if they also know how to prep it right!). I can say that ICI paints don't hold up the best. They chip quite easily and fade rather quickly. I always send my bodywork jobs to Valley Paint and Body. They do only Mercedes and do top notch work. Matter of fact, as soon as springtime rolls around, my 6.9 is going to them for a complete respray (it's DB904 Navy Blue--my favorite!). They quoted about $5,000 but I know it's worth every penny. As soon as I can expand my own workshop to accomodate painting, we will use exclusively Glasurit.
