Anyone know the weight of the gt500/mach1 spoiler? I definitely considering it. Just need to know if it’s lighter to help make me feel a little better about it..

I am not sure about the weight, but i was also considering a Mach 1 spoiler for my convertible. My question was related to corrosion. Is there a risk of water that would get stuck between the spoiler and trunk causing rust or other corrosion? If so, how can it be mitigated?
