What it's this?
i have flushed the system a couple of times and seen this before but not like this it looks fresh and is
gooey.
I Haven't used any additives.
the fluid was clear and does not show up on rad cap or coolant tank.

if you mix in tap water that can happen when the hard minerals react with the aluminum coolant passage. be sure to use bottled or distilled water.

Looks like you're using tap water. Use distilled water and some water wetter.

The only other thing that I can think of is that somebody may have mixed the dexcool (orange) type of coolant with the typical green coolant. When those two mix, you usually get some kind of passage blocking mud.

In general, most people dont know that tap water can be bad. Do not use tap water in anything you care about. I always flush the cooling system of any car I buy right away with distilled or reverse osmosis water.

Tap water usually contains electrically charged components, atoms and molecules that may conduct electricity, or rather, that can assist in the passing of electrons around. Distilled water contains no such charged ions and will not pass electrons- thereby preventing "electrolysis". Typical engines have electrons flying all over the place, they will move through any conductive medium, the intake manifold, the engine block, the chassis, and if you are using tap water: the water in your cooling system.
