SMART – BOND SOCK.
You throw it in your bilge and forget it. It will trap any oil, fuel or acid that it makes contact with and will even remove fuel or oil from water. Lasts until it has collected 6 litres of petrol per 30cm of sock.
Then it will remain in its solid state without letting go of a drop.

H Series for Synthetic Hydrocarbon Spills
Smart-Bond HS Polymer Encapsulating Absorbent has the ability to bond with synthetic and organic hydrocarbon spills including motor oils, brake fluids, transmission fluids and most liquid hydrocarbons, to form a solid mass. The bonding, encapsulating and solidification can be accomplished on hard surfaces and in water, producing a solid and manageable waste product that will not drip. The hardened waste product usually appears within 10 minutes after application.
HS Polymer suppress vapours and reduce off gassing by 80% in 5 min.
Completely hydrophobic and will float even after it is full.
