Well hi akshay. i really can understand your concern regarding fiberglass. well i had it too when i initially got into it.Well the TVR's are fiberglass, i guess even the older generation corvett, alfa romeo and some more too.
Also i would like to inform that the car is metal from inside and its just the skin on the body panels that are fiber. for eg. the doors will be metal structure but the outer panel is fiberglass.
i had crashed my bike some time ago and u had to see it to believe it. the fiber body had scratches and scrapes only to it..the bad part was that it was the metal handle and front fork that twisted.
Also i would like to point out that repairing fibre glass is cheaper and easier. also you don't have limitations of shapes on fiber. as you see metals aren't very flexible as once you get a shape u decide to change some features you just start over.
so for everyone i would like to ,in brief state how fiberglass panels are built.
1. stick blocks of thermocol on the naked vehicle. (the stage the car is right now)
2. with the help of sanding tools, we paper down the surfaces to the shape of the car we need. as in the final design
3. a coat of static thin plastic (food wrap plastic grade) is laid on the thermo col (fiberglass melts thermocol) make sure it takes the shape of the thermocol perfectly. even the most intricate surfaces.
4. fiberglass consists of three major parts.
a. fiber matt ( a cloth like material which is resemles plastic strands weaved together.)
b. resin-a sticky liquid
c. hardener and cobalt
hence the Matt is layed down on the surface. you mix the resin and harden with cobalt in a certain proportion. you then with the help of a brush apply the resin on the matt. give it time to harden (based on the amount of hardener cobalt mix). apply as many desired level of matt to get the desired thickness and strength
5. after the matt - resin mixture hardens up you take it out from the thermocol . you got a mold here.
6. Now from this mold you build your panels by repeating the same procedure with fiberglass on it. and release it from the mold.
7. now throw away the thermocol and start mounting the panels on the body
8. Finish with lambi, primer and paint .
