in our cars are some rusty valve cover.
some with a even layer of rust, some with the rust peeling off.
what to do about it ?
pitting corrosion should be avoided, i guess ?
should i use a wire brush or apply rust converter ?
maybe removing the oil with cleaning alcohol before ?
after having it off, one of you guys brushed it clean
and painted it black with something, i have seen somewhere here.
but since i wouldn't take it off now, i just like to conserve it a little..
