Can this be used on head lights?

I’m not sure I agree, I have been doing headlights in my downtime using High Solids Urethane Enamel for years and cars I did three years ago look good

What is the mix ratio?

Hello! Mixing ratio 4 parts clearcoat 1 part activator. Thank you!

Can this clear be mixed with another 4:1 acrylic clear brand?
