Yes, I'd thought of that (and I keep a bottle in
my tool box).
Problem is, there's a distinct crack to bridge where the 2 parts have
been stuck together,so the paint may well not last too well.
Depends on what stress it might be subject, I suppose.
Worse than that, the printhead is 1/4" wide, and
there are 8 tracks in
that width. I don't fancy trying to paint that lot without shorting at
least 2 of them together... Soldering on that pitch I could manage,
though, if only the solder would 'take'.
Ah. Given the thickness of the paint, painting tracks would be difficult,
even with a good-quality fine brush. The only other suggestion I can think
of, is to paint a wide strip, covering all 8 tracks, and then use a scalpel
blade (and some patience) to gently scratch gaps between them.
