Hi guys,
So as of last week I've begun molding my Daft Punk helmet replicas in latex. I've had to redo both molds after the first coat as they developed small air pockets/bubble which would distort the final cast. All is well so far on run #2, however after the third coat on my Guy Manuel helmet, three small bubbles have formed once again. I know for certain the first detail coat went on smooth and without problem, and that these only developed on the latest coat. I tried the first time around to cut the latex and place a fresh coat underneath to seal it, however that didn't work, the blade caught the latex rather than cutting it, dragging the rubber and causing a larger bubble.
My thoughts as to a solution (short of scrapping and restarting the molding of course) are:
1) Burst the bubble gently with a sewing needle and fill the entire recess with liquid latex, flattening the bubbles in the process
2) Burst the bubble gently with a sewing needle and apply thickened latex over the affected areas only, to flatten the bubbles and set/cure in the correct shape.
3) Any suggestions?
Of course, I'd like to avoid restarting the process and any help would be greatly appreciated.
Included is a picture below highlighting the affected spots. They're not too badly raised (1-2mm MAX), but a perfect cast saves time later on.
Thanks guys,
