This Solido dates back to the 1960s and was very good for the time.
More accurate in shape than the Teknos and Corgi fastback, the interior light was arranged to come on when the door was opened. I don't have the right battery to test that though.

David, That 1988 Ertl Mustang is hard to find, I believe. It is also more scale 1/48

Ertl Resin Police Cars
Hi Guys
A couple police cars made using a resin version of the Ertl model. Models never finished.

John, could you please tell us about the moulds? Why the holes?

RTV Molds
Hi Steve
These are simple two part RTV (Room Temperature Vulcanizing Rubber) molds that the resin is hand poured into. No injection pressure involved. Air bubbles will get trapped in corners, the holes with straws attached vented the trapped air. After pouring the resin, the molds are put in a pressure pot to minimize air pockets. In general this just pushes the bubbles inside the part and does not break up all the bubbles trapped in some areas. So you guess where the bubbles will get trap and put in a vent. It is much easier to file off a vent sprue that fill up a hole/pocket.

Molds some open with part still in cavity side. Molds are a HW Mazda (revised fenders) and camper shell for a CHP truck.
