Thanks for the ideas all. I got some good ideas. The fabric idea even made me think of some type of fabric rope! Something that looks nice and can just be glued to the ceiling and not the wall so there is room to move as you drive. Might look nice... also may look TERRIBLE! :)
I was familiar with the PVC stuff but the Home Depot near me stopped carrying it. I just ordered a nail gun and I will just try to FORCE the wood along the ceiling. I was trying to glue it with some fast set glue, but it was not strong enough.
But you all saved me a TON of time looking anyway. Thank you!
