Here's an update on my progress with trying to remake a upper door seal.
During this vacation I was able to spend some time on this project.
The second try turned out much better than the first with some exceptions.
Here is a picture of the mold (4 pieces) and the part.
Here is a picture of the part itself, just out of the mold.
The shape ended up pretty nice, even the really thin 1mm rib came out of the mold without tearing. As you can see, the color isn't right. The hardener I used was slighly old, and for some reason lost it's black color. The result is this translusant molasses colored part shown. Try 3 will be with some fresh hardener so the parts should look like the original rubber parts.
Don't know when I will get another chance but when I get some results, I will let you know.
