So as some of you know, I'm going to have my frame sandblasted and then powder coated. (S6).

I'm currently stripping it down. However, there's a few hicups. The push/pull tube for the elevator doesn't come out due to the rivets on each end. That in itself might not be an issue, but the sleeve it runs through seems to be plastic. I'm concerned it might melt when baking the powder coat. Any thoughts?

Same goes for the little plastic tube that the rudder cable runs through. I've removed the cable, but the tubes seem glued in.

And finally, I'm debating about the wooden ribs in the vertical stabilizer. Just tear them out and replace or keep them in and hope they don't burn up?
