Brite Tone Instrument Finish is a high solids, super-hard, scratch-resistant, clear finish with exceptional clarity. It is by far CrystaLac's hardest and clearest top coat. Brite Tone will build to a high depth very quickly due to its high solids content and will not leave a blue cast on dark exotic wood. Adheres to wood, metal, plastic and glass.

Brite tone

Awesome product. I became allergic to resin and thought I wouldn’t be able to make a tumbler. But, all was not lost, I found your products. Much easier to use than epoxy resin and a smooth durable finish. Thank you

I haven't used it yet, BUT

I got a quart of the Brite Tone and one of the Polyurethane at same time. The Polyurethane lid leaked and as everywhere! I contacted company with photos and they processed a replacement right away! This company has amazing costumer service. Other artists recommended these products and I can't wait to try them out!


It’s expensive
Requires many coats
Lots of dry time between coats
Upside is that it’s safe and non-toxic


I used it for tumblers but it just peeled off after a while


I love love love it I can make beautiful cups and stay safe and do what I love❤️. Perfect for me being that I’m allergic to epoxy Thank you guys
