while taking a splash off my sunroof i noticed that the plastic ends that stop the slider in the rail from falling out were cracked i decided to do a quick reproduction to get the sunroof back on the car.
here are some photos of the process. i left them curing overnight before i machine flashing off and drill mounting hole.

a quick clean-up

 

How was this done? You should make guage pods for the center vents in the eg cluster bezel!

 

Took a mould off the cracked originals with silicone then cast the replacements with 70 dura meter urethane. Pretty simple. Took a couple of hours.

 

Thats interesting, when you say silicone, your not talking about rtv are you? I know noting about this molding thing lol

 

No, these are moulding materials. Two part and made to cure when mixed.
