Do you have to paint over rust converter?

No. Although you do not have to paint after the Rust Converter application, it is recommended to apply a high-quality oil-based paint if the item will be stored outdoors. Surfaces protected with Rust Converter and an oil-based paint system resist weather, sunlight, rain and even salt spray without peeling or cracking.

Once opened must left over product be used up ?

No, jug closes and seals well. Have some product which is 2 years old and still plan to use it.

Is this a phosphoric acid based converter? Is it in gel form, so that it can be painted to the underside of a car?

Our Rust Converter has a Tannic acid base. It is not a gel. It is like a thin primer that can be easily sprayed or brushed on the underside of a vehicle depending on which formulation you purchase.
