The original is good for 600 deg F which for some applications is a must (I repaired a rust hole in an elbow in my boiler chimney several years ago - the repair is still rock solid)
I think the kwik stuff is only good for 250 deg F or so ....
I think it depends entirely on the specifics of the epoxy... the resins and hardeners used, and any fillers or additives.
TAP Plastics makes a nice range of "marine-grade" epoxies... one resin, three different hardeners. The mixed epoxies have significantly different viscosities, wetting abilities, and hardening times. The one I prefer as my "general utility infielder" bulk-mix epoxy is the low-viscosity variety, and if I don't add any fillers it's *quite* runny.
TAP sells a number of fillers that can be added to their epoxies, to modify the characteristics. One which might be of interest is "Cab-o-Sil", a very fine "fumed" silica that can make a liquid epoxy into a non-runny thixotropic gel, or a peanut-butter or petroleum- jelly-like paste.
Possibly, adding a few percent of a filler like this to JB Weld might reduce its tendency to be runny during cure, without affecting its strength and ruggedness. I would certainly want to try this experimentally before depending on the result!

Here's a nice, concise, page on the MasterBond epoxy range with a common frame of reference. (I.E. the table showing viscosity for common things).
Their epoxy range is 200 cps to 1,500,000 cps.

FYI,you can get West System epoxies and fillers at many marine boat stores,and also fiberglass cloth and mat for projects. That's where I bought my fumed silica;boat store.
One more FYI;
I have no financial connection to them.
