Chinook RV

This may work for black if its not the stiff stuff. http://a.co/g2Ix13n

I am still figuring out how to install mine in the corners, its very tough, looks like Chinook use some kind of adhesive in each corner, may I need to use a heat gun.

Yea might have to give that a try. I'm sure a heat gun would help with the corners, I've installed car molding in the pass like that.
