by the way, in researching refilling my canon inkjet tanks I came
across waterproof ink for the BCI-3e tanks.

Look at the top two items.

I have no idea if works as a resist but waterproof is a good first
step.  My printer (pixma 4000) doesn't have a straight through paper
path so it wouldn't matter to me.  These tanks go with a lot of canon
printers so maybe there is one that has the right paper path.
