Thank you for all your replies.

I agree with Simon in first hand, if the kit was mine, I'd go for a solid finish. I'll ask my friend about the options you gave me and see what he wants to do.

Btw, Simon, about the veneer:

Any of these bellow would fit? How to properly "install" it and finish? Also there's an issue with the back, would it be a also a good solution?
