Re: [TCML] Cleaning Copper Primary Coil (with Muriatic/Hydrochloric Acid)

Brandon,

The lacquer is much more durable than the wax.  The lacquer can be
sprayed on from a spray can... thin coats so it doesn't run/sag.
Various doorknobs and similar items are often lacquer coated so
they don't tarnish.  Sometimes the lacquer chips off in places
from rough handling, then those spots tarnish.  You may have seen
such items.   

Some folks use slotted plastic supports to hold the primary.  They
make the slots just wide enough so the copper tubing snaps into
the slots and stays in place.

Looks like I'll be whipping out that old can of Brasso. After hearing
about all the underlying grief with the acid, I think a little TLC
might be for the best.
So which is going to protect the copper best after I get it all nice
and shiny? The car wax, lacquer, or something else? I imagine applying
either of the suggested coatings would be quite the mess/complicated.
Unless the wax would just be applied with a rag like the brasso, but
then I'd be doubtful as to how durable that coat would be compared to
something else, like lacquer for example. I can also imagine the
lacquer would be tricky to apply throughout without making a huge
mess.

Oh, and one more thing. Hot glue or zip ties for securing the coil?
I'm also open to other suggestions of course. Those are simply easiest
and more or less preferred. But still, your ideas are invaluable to
me, I'm always happy to hear them. ;)

Thanks for all the help,
Brandon H.
