so i am building my 8mm chassis or half way built. I sanded the cut and glued with super gorilla glue which is thick like a med c.a. Then i hot glued some aluminum braces in the outside and inside of the car. Tomorrow i will cut a peice of aluminum very thing high grade stuff, brace the bottem with it and glue it then cover with contact cement, Should be better than one peice i asked my dad for help this time... lol i guess that is cheating
