Having problems with successive casts.
Roof is not the right shape with being concave or convex from cast to cast. Silicone mold is just too thin in that area for a correct and consistent contour.
Been softening up roof area under warm water and pressing against a hard, flat surface with mixed results.
Maybe just using filler and sanding will be fine in the end.
Yep, always something to deal with.
Not the end of the world.
