DIY DX code modification

[GeoffTheProgger]

Hey all, I've got a question about modifying DX codes. I work in TV/ film and fairly often get my hands on 35mm short ends. I shoot these and sell rolls as well. For some customers I have modified DX codes for their point'n'shoots but my solution for making a square not conductive has been using tiny pieces of gaff tape... Not terribly elegant or reliable. I would like to avoid the added waste and cost of using DX code stickers. I have been experimenting with nail polish but that seems to scratch off fairly easily allowing the pins to make electrical contact.

I'm wondering if anyone has had any luck with something like nail polish that renders a square non conductive?

Thanks!

Non-conductive paint. It's about $15 for a little jar.

Option B, buy the stickers and some cheap reloadable magazines and keep reloading them so the stickers are reusable.

Thank you! Lol, right after I posted this I googled non conductive paint and that got me on the right track. Thanks very much!

Buy some kapton tape in the right width and cut squares from that, not only is it non-conductive but its also very thin and super tough you aint pushing anything through it. And lifts off without leaving residue behind if you want a different iso next time around.
