Tiny bubbles in new surfboard

bump

It's kinda hard to tell what might be causing them...dust maybe?

My guess is that they won't reduce board strength but it's reflective of quality. If you're in a position to speak to the shaper and feel comfortable doing so, I'd bring it up with them. Keep the tone inquisitive, not accusatory.

Can’t quite tell in the photos but I’d guess either air bubbles in the glass or else in the foam where they sanded the blank down to.

Weird ...
Zoomed in ,the dots seem to have linear and parallel pattern like fibreglass does . I doubt it's dust or air bubbles , I'd assume they'd have a random pattern.

Maybe shingles then TS?

haha , wrong colour.
It looks like braille to me . The shapers not vision impaired is he...?

Could be "drain out" , if the resin takes a bit long to cure ( too cold or not enough catalyst usually) you can get bubbles or whitish cloth look a bit like what you have in that picture ,the resin literally drains out of the cloth instead of setting after lamination , ugly but not really structural , they would have sealed it when putting sanding coat on after most likely. That is with polyester resin. I am not that familiar with epoxy , that board maybe a epoxy by the looks? HS? so not 100%

Chinese epoxy board.??

I've seen that before but it took a while to click , I've seen it on boats , .It looks like 'osmosis blistering'. In which case is very bad.
A photo in this link is very similar.

But I'd be taking it back if it was new , not repairing it.

How could it happen to a new board.??
Probably glassed it with moisture in side the foam in humid conditions and the problem could be made worse by storing the board in a salty boardcover .

I'm not categorically saying it is that , but it certainly looks like a good possibility.
