I haven't heard anybody mention "Everbrite" in YEARS, but I have and also have USED it (many years ago).
It's a strange wipe-on (or you can use a brush or sprayer) resin that the makers are very cagey about spelling out exactly what this stuff is made from.
But they are clear to say you need to use Nitrile gloves to avoid skin contact, and use serious respirators if you spray it.
But BITD I had good results with the stuff. My sales contact was in Nevada, IIRC
