Petseal Ultra Sealant
The original and the best!! Simply add the hardener and swill around the base of any tank to fill pin holes or stop loose rust from entering the fuel system. Comes in 260ml cans suitable for small to medium sized tanks, use two for large tanks.
The Quantity of petseal required will depend on the size and condition of your tank. One 260ml Ultra pack should be sufficient for a 15 Litre tank with light rust. A heavy pitted rusty tank up to 25 litres would require one 500ml Ultra Pack
Priemium and Ultra should not be mixed together
