My process should also be found in the archives and does not use renite but the cork I use is far finer than 40/80 grit- I don't know the actual grit size but would guess 220 and above,- its like very fine dust. If you blow on a handful, a lot of it will stay airborne a long time
A common cause of scratches even in a good pasted mold is not keeping things clean- like putting the mold on the floor when blowing and then polluting the dipping water with dirt from the floor. Even dirty water in your block bucket. Everything has to be clean and kept clean- change water etc.
Of the other thousand variations, blowing too hard or staying too long in the mold, will do it.
