It's absolutely permanently in there. Of course, there is a bright side I realizeed too late to use this piece. All the excess can be trimmed away and it would be just fine. In fact, that's exactly what I did with the front exhaust pieces. |
| David Duckett | Dumas Kit #503, Boeing AV 8B Harrier | Reference | 02-Dec-09 11:20 |  | | Views : 1021 | | This is how they look unmolded. The pieces with the blue plastic practically fell out. The flash around the pieces can easily be trimmed away with a razor knife and then sanded. The halves can be glued together with plastic cement, or CA if you're brave, and then sanded and filled with filler before painting. They are fairly heavy for their size. The instructions also come with a pamphlet showing how to make molds from parts. This is all I do with the stuff, Pfinn makes much more with it. Much more. |

When it no longer feels sticky it's ready to unmold. It gets warm while curing and thicker concentrations cure faster. To unmold, bend the plastic away from the mold and..... |

| David Duckett | Dumas Kit #503, Boeing AV 8B Harrier | Reference | 02-Dec-09 11:06 |  | | Views : 712 | | About 10 minutes later the curing process is well underway and my faith in chemistry restored. I always have serious doubts when I first pour the clear mixture in the mold. |
| David Duckett | Dumas Kit #503, Boeing AV 8B Harrier | Reference | 02-Dec-09 11:03 |  | | Views : 725 | | THe mixure has been poured into the molds and has cleared up. This is good. |
| David Duckett | Dumas Kit #503, Boeing AV 8B Harrier | Reference | 02-Dec-09 10:57 |  | | Views : 671 | | The two parts have been shaken and then allowed to sit for a minute or so. I poured in 1/2 oz of part A and then 1/2 oz of part B and have gently stirred the mixture with the stick and it still has a slightly milky look but that's OK. Instructions are included with the resin. The idea here is to get rid of all the tiny bubbles. |

Spray the inside of the pieces with the release agent and then wipe it with the soft brush. Spray again and let sit 5 minutes before using. NOTICE: The blue plastic covering the clear part has NOT been removed. |

The release agent is #82664 Rubber To Resin Mold Release- $17.50. Mixing cups, a stick to stir it , and a soft brush are needed, as well. The plastice pieces are from Guillows and Dumas kits. |
| David Duckett | Dumas Kit #503, Boeing AV 8B Harrier | Reference | 02-Dec-09 10:44 |  | | Views : 766 | | As per your request...Micromark.com has lots of goodies for modelers. This is part of the casting stuff and there's more but this has what I use. Following is a "how to" on using the stuff to make casts from the plastic pieces in typical balsa and tissue kit. Perhaps James can put it in the official place...:-) |
