Hi folks,
I am new here so, excuse me for for stupid questions.
Here it is:    I have a lotus Elise S2 unpainted sill panel ( new) and intend to make a mould of a segment of that sill.   Can I use any kind of release agent on the actual sill, or do I need to get the sill painted first  ?  What release agent assures me that the original sill is not going to be damaged and at the same assures me that the mould can be released ?   Much appreciate... you can see the part that I am going the create in the video.  on side of the car has the tip of the sill and the other not.  You will also see the overall new sill.  https://youtu.be/BNj6ELbmqao
