Silicon mold making.........School me please.

[slocrow]

Some time ago, NZSimon mentioned that he made silicon molds for the production of some taillight buckets.
What type of silicon should be used and what would be the procedure to make a reproduction of the recesses in the trunk lid skin and back side for the buckets, assuming I can find a donor trunk lid from which to make a mold......Thanks, Frank

The smooth on website already has most of what you need to know

if the part doesn't have any overhangs or is a simple shape you can use plaster of paris or even body filler or spray foam gapfiller you can buy at any dept store hardware dept

if you do use silicon make sure you apply a thin coat first with a brush or similar so as to avoid surface bubbles

most of the setup time depends on wether you want to use it more than once
