I've got this custom made foil board.
There are some marks that have appeared - they're mainly on or near the rails on the top side of the board.
I am curious to know what the cause of these marks is.
The guys from the shop that makes the board reckons they are from small impacts, like contact with the spreader bar etc. I'm not so sure - I can't see any signs of impact on the surface. I also haven't had this happen on any other board.
If I had to hazard a guess parts of the lamination have ended up dry, i.e. resin starved, and the fibreglass has become stressed /damaged at those points.
It may be that they may have glassed too many layers at once. There's apparently 5 layers there.
Anyway truth is I don't really know - thought I'd put it out there on the forum and get a more educated opinion.
