Rich-
I have a pal who bought a can of Kirker Mack Blue ( I assume you are considering that) to repaint his Suburban. Unfortunately, he hasn't gotten around to it yet (and won't be in town for awhile). I am seriously considering this paint for my W116, whenever
I get around to that.
You can call Kirker and get a REAL paint chip chart (free) to give you an idea- much better than the web
There was a place I called a few weeks ago ( discussed on Autobody101 forum)that seems to have custom Valspar paint at very reasonable prices. I was calling for Maple Yellow urethane. Probably will be pricey in blue. This place:
