Def could be. I just think its odd that the color continues onto the bottom cutlap. Seems hard to do with a foam stain.
Depend where you put masking tape no?
You probably can turn around rails like with fiber.
Even if i don’t do it, the look of my board is simple and come from tech, i bet foam stain is easier than tint in fiber because you don’t have to care about right soaking, chase bubbles, etc. And after stain is cured you laminate on a closed support, harder if you use resin stain, so all what make lam fiber easier. That’s like sealing eps foam, you can not do it but you should…
