I pour it in a spray bottle and use disposable wipes. It goes away fast.

I really doubt that stuff would do much against the formidable asphalteum. Have you used it on the stuff in a bus?

I used DupliColor Paint Prep Spray (most auto parts stores)...and it did a darn good job on 70 year old, rock hard asphalteum.
