Is it necessary to sand rusted surfaces until the steel is shiny again before applying CIP?

No. CIP can be applied directly to oxidised surfaces, but it is recommended you brush the surface with a wire brush to remove the worst of the rust.

What finish can you use on top of CIP?

CIP can be covered with all types of finish.

Can CIP be used as a finished product?

No. CIP is a primer and isn't designed to be used as a finish.

Once dry, how long can you leave CIP exposed before covering it?

Ideally, CIP must be covered as soon as possible after it has dried to avoid possible contamination of the surface.
However, if conditions won't allow it, it can be left for up to 2 weeks. When covering, it is therefore important to ascertain whether the CIP's surface is clean and uncontaminated, to ensure good adhesion of all the finishing coats.

I've got a swimming pool shelter in aluminium painted with brown Qualicoat (in March 2006)...

After have cleaned the surface and eliminated all the non-adhering parts, you can apply RUSTOL-OWATROL, which should be covered with a glycerophtalic or urethane alkyd paint. Or, you can use RUSTOL CIP and cover with the paint of your choice.

What are the differences between OWATROL CIP and MARINE OIL?

OWATROL CIP is a penetrating coloured anti-corrosive metal primer that can be overcoated with any type of paint, it may also be applied to new or brightly cleaned metal surfaces. MARINE OIL is a clear penetrating oil that can be used as a conditioner for any coating where the clean up is specified as mineral spirit. MARINE OIL is also an excellent rust inhibitor but may only be overcoated with oil/alkyd or water-based paint.
