You need to ensure it can't move though, otherwise it could change shape in the heat- If it's in a (much thicker) mould whilst it cures then it's very unlikely to sag. If the part isn't in a mould to stabilise it, it may be best left for a couple of weeks in room temperature, maybe left in position in the car?. I know someone who had an old kit which had never been built, and the bootlid hadn't been stored in position. When he offered it up to the car is was clearly bent by a few inches. Held by wood and braced over a few months gradually bent it back to its correct shape. Some people advocate the blue PVA release agent, but I had a part stick using it (similarly made the mould a few days before) so I've never trusted it again. I've heard others have poor results with PVA also.
