POR15 engine block filler For aluminum

Buy on Amazon

Por15 offers a variety of filler for personal choice and yet maintaining quality in all the variants. This size is more than enough to seal and restore a 3 gallon Honda ATV tank. It is specifically formulated to provide a permanent seal with superior strength and resistance to all fuels, including the new stage ii fuels which have a high alcohol content. It will flow downward and settle on the bottom, leaving a thin coat on the sides and a thick coat on the bottom. It is coated with plastic after removing the old coating.

The viscosity is very low so the solution will flow freely and thin on the surface coated. It is easy to use, low odor and no heavy paint smell. The sealer dries to a very hard, almost ceramic finish. It is essential in preventing rust and corrosion for long lasting results.

• Can be used in any gas tank
• Great stuf for old kerosene lanterns
• Works great even without the degreaser and prep kit
