Exterior Weather Strip

Use an air-release cast vinyl, you'll never have bubbles again. 3M 2080 series vinyl would work well for this, as well as Oracal's 970RA. I've wrapped tons of trim in the past, its not hard to do and looks like oem parts and not wrapped with vinyl in the end.

lol! I dunno about that!!! I did my truck's trim, it was pretty beaten up, the supra's trim is still in perfect condition though. Think I've wrapped trim on at least a few dozen vehicles over the years though, just take your time, start from the center and work the vinyl down towards the edges. Also remember, any imperfections in the trim will show up in the wrap, so make sure they're sanded well and spend the extra time going through several grits to get rid of all the small scratches!

Heat it if its really not behaving or you've overstretched it and need it to shrink back to its normal size. I also use heat as a final step to "lock it in" to the vehicle. The vinyl is extremely good at stretching without any heat on its own, and once you get a feel for how the vinyl acts, you'll know just how far you can stretch it before you start seeing it in the color or sheen.

One other thing to add, too much heat on matte vinyl will make it shiny!
