I just tried making a silicone mould from a master which all seemed OK but after I got the first piece out of teh mould there were a lot of dust marks on the  piece. I presume the dust had been attracted to the mould surface. Am I doing anything wrong?

you know i was like mad when first putted carbon then resin , next brushed dry 120 then 180 and once again and started to leave tiny holes filed white so i started to use this method not clean surface before laying Nefrase but i cleaned by - Acetone and they done all bad things i suggest. and what i recently found i always had problems with bubles tiny that leaving after i laying with brush resin - problem was cheap simple brush so use hardly flexible brush as with soft brush you gonna kill yourselve with playing with bubles. i hope my exprience helped.
