I've used products that were listed as "black" for 30 plus years and found it to be a very close match to original so the term gray can be IMHO misleading. Also many restorers back in the 80's (and copies of the product sold through Mustang parts houses) use the light or medium grey since they was what was available as "NOS" so that mislead allot of people during that period.
As far as the MAC stuff I've never ordered or used it - sorry

Very Dark Gray +1 . The Mac strip caulk product can be seen poking out of the bottom of the package in a enlarged picture . Going strictly by the image I see represented in my monitor it appears to be more of a medium gray. I have not used that specific product ether so I don't have any more of a impression other then the picture provided.
ExportMach:
While resto-modding my 65 coupe I found a box of caulk rope by 3M . . . I believe it is a med. grey.

They and other suppliers make a dark grey /black product. There is a fairly long thread that was posted a while back discussing the change in the 3M product, other suppliers, comparisons and related details that I suggest people interested in finding and using seek out using the search feature here
Bossbill:
Getting back to this . . .
The rope caulk I got from a fellow restorer had no gray in it whatsoever. Jet black.
I don't know what med gray or dark gray means as that's quite subjective.
How about we use grayscale values?
Here are 8 different grays, according to their grayscale values (here it's called Grayscale 235 descending to 75). See attachment. Which one do you guys like?
[any good drawing program could replicate this for your monitor/printer]
When applied to the gas tank and fender area (SJ Mar) how much should Goosh out? Yeah, Goosh is a technical term!

Gas tank typically very little - more (slightly) looking from underneath
Here are some examples. Less product used to seal compared to the fender application. Remember the color of the strip is affected/changes over time and with exposure to the sun and the air
Fenders often none IMHO was not covered. Every once in a while you might find a car where the end of the strand slide out but from the tens of thousands I've seen this was not the norm. Many of the picture threads of unrestored 67 San Jose and even 68's here on the sight will provide you with some examples
Will start a new thread in the 67-8 Section so that it makes it easier for other members to find the fender related information if its not buried in a discussion about gas tanks
