- Place the OTT (Over-The-Top) coated part into the middle of the tray (Still making sure that the 2nd layer of liquid rubber is only partly cured...) and also making sure that the last part of the piece you touched has also got a VERY generous coating of petroleum jelly on...
- Next, add enough liquid rubber all around the part NOT ON TOP OF IT, and in all the holes and gaps just enough to "just-about" reach the top of the part....
- To get most of the air bubbles out to the top, pick up the tray and only from a distance of roughly 15cm ish, GENTLY drop the tray onto your flat surface about 5-6 times, DO NOT do this too much or the petroleum jelly will become mixed in in-accurate places and your mold will not be an almost or exact copy and when its time to start using the polymorph the mold will be a very odd shape...
