Which is more dominant, the burnt rubber or the choc/mocha?
From your description it sounds like the diesel is the main smell with undertones of choc/mocha.
Yes I would say the diesel is Dom in perfume dep. slim jims and sour burnt rubber extremely over power everything in here, almost a gross smell, but very pleasant. The sour mocha fades in and out through whiffs, and seems to be the last fainting smell after a breath.
Starts with strong slim jim smell, followed by sour burnt rubber finishing with sour mocha slim Jim with a hint of a light roast coffee bean. Best I can descript it.
