I want to make a mould for a clear headlamp cover on a sports car. The body is unpainted (right now) frp, If I could fill the 'socket" in the front of the car with an expanding foam and work it into shape after it hardens then I could get a positive, and then vacuum-mould a bit of acrylic or polycarb to match. The fellow doing the body-work and painting would like it very much if this did not ruin his nice work. If there is not a non-sticky foam then what should I use as a release agent - could be something as simple as parchment papaer I suppose...
Is there a foam that would suit?
Any other suggestions welcome.
No, these covers are not otherwise available.
