It looked pretty good and the price was right so I ordered some. Did a lot of testing with different adhesives but none came out smooth enough for my liking. I decided to put it on with no glue and staple it on the edges. The vinyl has some stretch to it so I just worked my way along stretching and stapling as I went. Anyway this is what I came up with.
So far I haven't seen any bubbling or ripples in the vinyl and the staples are holding strong. If I made a mistake I can always redo it later on.
Also you can see my "curved roofline with a flat vent" in these photos. It's worked out pretty well. I did use some PL adhesive to hold the vinyl down around the vent opening.
That's all for now. Later.
