I'm helping a buddy repair the nose of his board and while my PVC sandwich skills are pretty solid, I'm not sure how proceed with a wood veneer board (EPS, veneer, glass - usually the mid-grade construction for a lot of companies). Should I just use extra glass in lieu of the veneer, PVC, or is it necessary to source some decent veneer? A bit of extra weight isn't a concern, I just want to make a solid repair so the next time he foils out, the board won't end up without a nose.
btw. it's going to be covered with paint so don't need wood for aesthetics.
For a nose job its irrelevant. Just extra 2 x 4oz ish.
For a structurally important area I try to use same wood, but if I can't then I find 200gsm unidirectional carbon is a reasonable replacement as it seems to be similar strength and of course unidirectional like the wood is.
An engineer will pop up now with tensile MPa elongation at break density kilojoules and tell me its wrong 
Mark _australia, perfect - I really appreciate the quick yet detailed answer. Thanks so much! Depending on how nice he is to me, he'll either get glass or cf. 
Don't worry about the engineer. The epoxy will have set by then and I'll be getting out the rattle can. It'll just be our little secret.
For noses I really like using a PVC foam block. Yes it's slightly heavier but it's also VERY strong and easily shaped. I've had boards that I just added more glass and had it crack again because the EPS just doesn't back up the glass well enough.

We dug out the bad foam and replaced with pour foam which seems a bit stiffer (2 lb iirc). Not as dense as PVC but should make things a bit more meaty up there.
Definitely an idea to keep in mind.
