Body/floor/interior rivets and rivnuts

[Ben_Copeland]

I would worry about steel rivets rusting as they aren't painted etc. Aluminium rivets are plenty strong enough, they are used in planes! Make sure you use closed end rivets

I don't like rivnuts, they have a horrible tendency of spinning with the bolt still in them

I ended up tacking the rivnuts to my chassis where they hold the nosecone on. The only other body part held on with them is the scuttle.
