When I was working on a mustang, I couldn't find the door lock gaskets and also couldn't find one of the gaskets for the door handle (which I later found) so I made my own as I didn't want to wait and send off for them (yeah I could have just probably cut some out of a piece of something, but the one for the handle has an impression and the outside of the gasket fits around the outside of the handle, so it is not a flat piece. I don't think there was door lock gaskets when I got the car. This would also work for other small things like hood bumpers, ect, and I've even copyied model cars this way. First you need to make a part that will be copied (or already have the part to copy). I cut the shape of the door lock gasket from a piece of soft plastic about the thickness I wanted from an outline I found on the web. Once you have the part made you want to copy, apply a wax (I used some paste floor wax) for mold release to the part and place on a piece of waxed paper on a hard flat surface. Then you need a box or something else slightly larger then your part. I used a cap from a jug of cleaner. Mix up some plastic filler and fill the cap, plaster of paris would also work, and while its still wet tip it over on top of the part and leave it harden. Now you can remove the part you used to make your mold and you now can make copys. I used some flexible bumper repair material I had around to make some gaskets, but you can use whatever material you want. Just make sure you wax the mold you made before making your duplicate parts. More complicated parts the mold would have to be split to remove it from the part you are copying and also to get the parts you make out of the mold. This could also be used on a larger scale to make a fiberlass part or maybe a repair peice for a corvette, depending on your dedication. Something larger you would build a box around the part you want to copy, and fill it with plaster to make your mold. Then you can wax and lay fiberglass up inside the mold to make your peice.

That is a cool idea..I like the part about making glass parts from a mold like that if a fellow has a good piece to work from..
