OK, heres the deal. The product is called HTS-2000, it is a fluxless welding rod, consisting of 9 different alloys, the main one being aluminum. Apparantly though they wont tell you what the other 8 are because of \"trade secrets\", but the msds says it is harmless.
you take a propane, butane, or oxy/acet torch and heat the repair area, placing the rod on the substrate you just heated, it begins to molten because it has a much lower melting point than aluminum. you spread it around the repair and as it cools it becomes way stronger than the aluminum.
the demo consisted of poking a hole in the bottom of a pop can, about a 3/16\" of an inch, she began to heat the bottom af the can, filled the hole, and when it cooled the pop can folded around the repair when we tested its strength.
very cool stuff but a bit pricey, she wanted $150 for a pound of welding rod.
the video showed repairing cracks in trannys, making new threads in a stripped part, repairing damaged a/c lines, etc, etc. it is also polishable, so doing those moldings would probably work out.
If my company buys some, I will secretly \"borrow\" a rod or two and try them out on moldings. or if interested I can give you contact information, and you can see the demo yourself.
