I think if it was tar there would be more tracking from the feet. Almost looks like marker
I agree.
It does not look like any of the tar I have come across.
Looks much too "thin" and uniformly spread to be tar, but none the less, glad it came out.
Spring brings the tar around here as the roofing season picks up.
Surprisingly EASY to clean if your not a total spazz and make more of a mess by spreading it.
I find the key to be to take your time with the primary towel BLOOTING phase and to GRADUALLY dissolve and transfer the majority of the solids to a towel before any direct "heavy"direct topical application of solvent is applied via spray or quirt.
Surprising how fast tar can dissolve with a good solvent, so gotta be careful not to liquefy too much at once and let it move deeper down.
