I just picked up some GFX, and it has a little damage that needs repair. So what product should I get to fix plastic pieces, like the nose cover, quarter panel pieces, etc. Something like bondo for plastic. Also where can I get this stuff at.

Thanks

 

SEM makes a flexible parts filler that works similar to regular body filler, except it is only for urethane parts like the nose and rear bumper. It is available at automotive paint suppliers.

If you have a 'bird then the rocker panel gfx are also urethane. If you have a Camaro then they are fiberglass composite, and you should use fiberglass resin and mat. The door pieces on both cars are fiberglass.
