Anyone know, come on guys, anyone that has built skis know?

I am about to satrt building but i have one quick question. I want the top of my skis to be all white but i want to put some blue die cut logos under the top sheet, so my question is will the die cuts show through the white top sheet or do i need to use a clear top sheet? If i have to use clear then...

Where can i get some MDF to build my mold? I cant find any suppliers online. Anyone know? Thanks.
