Can it be used without the wand, like a spray can?

Thanks for asking. Yes, this can be used without a wand like a ordinary aerosol spray can.

Can it be used on a warm item like a transmission?

This is a wax type substance that I used to seal the door cavity in my Chevelle. I would not recommend using this product on parts that get hot for extended periods of time i.e. transmissions and engines

Would this work to stop rust. Inside of rocker panels or slow it down?

It wont stop pre existing rust but may slow it down somewhat. It is designed to be applied to properly prepared metal.

Will it damage wiring?

No , it's a liquid wax , that dries to a soft wax , totally awesome for boxed frames
