I have an underground storage tank (kerosene) that had 2 copper pipes which were terminated and covered with cement and some type of epoxy patch. The patch failed after 13+ years (we bought home not knowing about the tank)�had the cement removed enough to see only one of the two copper pipes was crimped�the other one had a sliw frp�that has been crimped and epoxy applied but basement still smells of kerosene. Does your dynaseal product seal cement so we won't smell kerosene? SAMPLE - AFM SafeCoat, DynoSeal Concrete & Masonry Sealers

Maybe. We've not tested it for that type of odor, but it has worked for similar odors. It might require 3-4 coats to fully block the smells. However, make sure the surface is dry as this will not bond well if applied directly over solvents such as kerosene.
