Can the ESC of HBX 2105A RC car be upgraded?

HBX 2193 Is the shell of the remote control car scratch-resistant? I like to play violently, but I’m afraid that RC cars are easily scratched. Do any players have this car? Can you tell me if it will get scratched easily?

HBX 16890A Will water in the RC car shock affect the performance of the RC car? Will it rust? Because I want to put the HBX 16890A RC car into the water to play, and I am afraid that it will not waterproof the shock absorber, thus rusting and affecting the performance of the RC car.
