if that is not obvious to you, you must be an alien.
A household radiator is cast iron. An automotive radiator would be aluminum or copper.
Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.
Metal
It's pretty easy to find a chocolate fountain. However most of these fountains are made of metal, that is heated, because all surfaces must stay warm to keep the chocolate liquid.
chocolate was made when chocolate was made
When mixed with coolant in the radiator it tends to look like a chocolate milkshake.
Your radiator cap is made of metal and rubber. The metal and rubber are reacting to the rust in your radiator. Rust and oxidation in your radiator will deteriorate the cap at an accelerated rate. I suggest flushing the cooling system and replacing the coolant and cap. If it persists after that you might have a heat problem that is cooking the rubber right off the radiator cap. If this is the case you should check your thermostat and heating Coil.

The first chocolate made was hot chocolate.
On my 91 it is metal (copper, or an alloy I believe?), although I have never heard of a plastic radiator.
