Jake; all the information I have is from what was written on tape on the cans. This is NAPA info and the Juniper Green is 655. The paint I used on the interior only says - "BMW trim, 97'-2004". That may not be much to go on especially the interior paint but I found it to be a very close match. I may have used a touch of flattener in it, been too long and cannot remember but the finish seems right. The green I used is a single stage acrylic but works nicely. I don't know if it is lighter than Forester Green as I had no reason to look at it.
FWIW, I have in years past used a great deal of PPG and Ditzler. I loved the way this NAPA (S-W)paint covered and flowed. I would use it again in a heartbeat. One of my major customers has a large fleet paint business and uses nothing but Sherwin Williams, now I can see why.
