Foam Lux isn't EVA foam, it's a plastazote LD45, that means it's softer compared to normal EVA foam.
Foam Lux is suggested to cover the led light in order to achieve a good diffusion effect of the light. 1 or 2 layer are suggested depending on the led power.
To dye the Foam Lux you must use a primer before, like our Hexflex primer transparent, and then airbrush painting with transparent colors, like the glass colors, and final transparent top like Valour Clear Coat. Instead paintig it's a solution to use colored led light and finish the Foam Lux with only primer and top transparent
