ok, some things are: make the vinyl u cut out, quite a bit larger than the trim. u need it to fold around the corner and glue it a bit to the back also. try to get a roller as i mentioned before, to get it all pressed in on the corners and edges. if you roll the edges, it will make any fold you do look smoother, as the vinyl gets softer after you work it a bit. glue it an inch to the back as well if you can. glue it from the front of the trim first obviously. you shouldn't need any weight to hold the vinyl down. just roll it on, then let it sit for a while. after that bit dries, do the edges and the back. you may need to put some sort of weight on the back part when the glue there is drying. dont clamp, unless u use some foam or something. its very easy to mark the vinyl. white should look cool. i was thinking of that color too, but grey won on a toss up. moo cow totally lost
. if i can think of any other things ill post later. just gotta fly out at the moment. good luck mate
