Quoted from Freeplay40:
Been a lot of request for both of them actually. The biggest hurdle with these two ramps is the type of plastic to use. Since they have been prone to damage I would be hesitant to use acrylic for them. Further, I could source the red in acrylic but most likely not the yellow (Note that only extruded Acrylic can be vacuum formed and while most any color is available in "Cast" Acrylic, the choices in extruded are very few.) Ideally these ramps will be formed with PETG which unfortunately these days in only readily available in clear. Custom colors can be sourced overseas but are subject to minimum orders, like 2000 pounds.
That leaves only two other alternatives.... Clear that is painted or what I will be testing soon.....dyeing.
I think both GNR ramps would look fantastic as clear ramps, with a yellow/red third-party wire lighting solution following the edges. There's so much color on the PF as it is, I think I'd actually prefer them clear, or the gunmetal/smoke of the G prototype that Dave was looking into.
