Brian - the vinyl goes down nicely, however, I was not impressed with their recommeded glue. I used it, but I used the 3M spray for corners and edges, as it tacks up really fast and seemed to hold well. Of course, working with wood, I was able to secure everything with Marine staples.
I can't be sure, but I don't think this is the same as what War Eagle uses. Here is why I say this - I have a 1999 War Eagle with factory vinyl. There are a couple of tears in that - it has a more fibrous backing than this stuff. Newer War Eagles might in fact use this stuff...don't know.
I would not hesitate to use this stuff - at least from a workability standpoint. It goes without saying, it shows your errors more clearly than carpet - so measure twice and cut once. (The aluminum and the vinyl.)
