Hello
When the resin has cured, and I start to sand with grit 320 sandpaper, tiny white spots appear on top of the resin. I estimate them to be around 1/10 mm each... I presume it is sanding dust finding its way into airbubbles, that I have "sanded open".
How do I avoid those spots? Is it something I'm doing wrong in the pouring and curing proces? In the sanding proces? (wet/drysanding)
I am using epoxy casting resin "water clear"
Kind regards
Bo
