I'm having trouble getting this exotic polish. Anyone have a supplier they recomment?

Incidently, I just applied PhotoBlocker on my licence plates and
about to consider it a hoax. I used my camera to taking pitures such as a traffic cameras would. But the images only faded out the state and years around the periphery of the licence, but didn't degrade the raised numbers. Time will tell but meanwhile I'm not recommending spening $35 for the unknown efficacy. Thinking back I feel stupid falling for this but they did have a Fox News report with the Denver PD.
