Paint formulations are a very highly guarded secret among GOOD manufacturers. Glow powder is also very expensive and small companies many times don’t use enough or use a clear that dulls it. Red & Blue will never glow as long as green under any circumstances but should glow less longer. I can only attest to my past time with Lindy products, Techni-Glow was a great product and closely watched for quality. It’s also a hard product to get to stick and cheapies chip off easily, I bought some Neon Lites that all the paint cracked off when I cleaned the eyes!
