Homebrew PCBs

Those tanks are actually molded from two peices and
glued together.  I have had several over the years.

Some HAVE leaked at the glue seam.  Now I am using
an acid based etchant the latest tank I have is
developing crazing and slow leaks in the walls.

I do store it ALL in a large HDPE box though so
leaks are not catastrphic.
