searched this forum, lots of topics about 'clouds', 'dots & spots' but couldn't find a specific answer to my question.
I use the easy comp fusion fix to stick the fibre to my pieces. As i have a vacuum machine, for the first layer of epoxy (EL2 also easy comp) I use vacuum baging.
after vacuum, on the first (tacky) surface i use 2 other layers of epoxy (hand layed) for thickness.
Now, in the last pieces, I saw white dots. it it possible that (to much) fusionfix dissolves ? or do i need to search in the regular temperature / humidity problems?
