Does plastic wrap stick better to plastic containers or metal containers?
Plastic wrap sticks best to glass, but it also sticks to metal. For plastic containers, try aluminum foil.
Assuming the plastic just melts and doesn't undergo a chemical change through carbonization (i.e., you burn it), it shouldn't stick to any iron-based metal. "Sticking" is related to the smoothness of the surface of the mold. If you mold has a mirror finish, you should be able to simply peel the plastic off.
That depends on the pan. If the pan is covered with a non-stick coating such as Teflon, then scratches caused by a metal utensil can degrade - and even ruin - the non-stick finish. Of course, even wooden or plastic tools can damage the finish if you are not careful. If the pan is steel or cast iron, then a metal utensil will not damage it.
Any field hockey stick containing "metal or metallic compounds" is explicitly forbidden and nobody makes them at all. Ice hockey sticks may contain aluminum (a light yet strong metal). THese are usually not completely metal, but have a metal shaft and wooden blade spliced and glued to it. These are not in common use because of how hard they are, and the inaccuracy of the join between blade and shaft.
I don't know how envolved you want to get but, your problem is the plastic will flex and the paint will chip and peel, you need two (2) things, a bonding agent (to make the paint stick to the plastic) and a flex agent (to make the paint stretch). you can get these at a automotive paint store. Its a little envolved but I have never had a problem with peeling or chipping paint on…
