What would happen to the metals if iron nails were used to secure sheets of copper to a roof?
my spelling is bad butt to answer use copper nails and a rubber garment aka rubber oring and ya should be good on eletrictalasess
If you have a bad gas problem, additives can be of help, but the effect they have on most cars does not warrant the expense. In winter STP gas additive will absorb moisture and prevent gas line icing.
I do believe in using injector cleaner once in awhile. I dont know about all the octane boosters so on. However Premium gas does usually contain less crappy polymers (stuff to gum up injectors) better/more detergent properties. Even if you're car doesent require premium most regular is far inferior in chemical composition. What a shame huh. Thats why people use premium when they know they dont need it. Sometimes you still get contaminated fuel that wont work right under any circumstances.
You will have rotting nails in the future, its a greenish color. Copper and metal dont mix.
Consult the galvanic scale. Copper is 'more noble', i.e., less active chemically. If the two metals are immersed in an electrolyte, i.e., a conductive fluid, the copper and iron form a weak battery and the copper, over time, eats away at the iron as the electricity flows between them. fresh rain water isn't a good electrolyte like sea water so it would take a while, but the copper would rot away the iron. That's why when they install a copper roof the copper is held down with nails that are covered over by successive sheets of copper, to protect them from rain.
