>>>The body shop doing mine said they'd have to put mad support on the back side to make it strong, and that would be heavier. <<<
There is no reason it has to be much heavier. At a guess the 16 inch crack when repaired might be a pound heavier. Maybe less. Very few shops know how to do FG work though...that may be part of the matter in many cases. All shops know how to unbolt and rebolt stuff (or should!).
The Lotus Europa Service Manual shows how to do fiberglass repair in it...wonder if the Elise book does the same.
If you post PICs of FG damage to the Seloc guys, they could comment on it. Since over there many of the shops do know how to repair FG.
