I did baja the last 4 years at NC State, we didn't think y'all had a team anymore, just a formula team. Did you go to any competitions this year? Here's the car we competed with this year. View attachment 223312
I recall one year the state team built a car using 7075 alum. To keep the treatment, they used aircraft epoxy to hold it all together. You can guess how that worked out for them.
