I've used B2B in the past and have been fairly satisfied. The only problem I've had is that it tends to run a little in the rain. Alternatively, I've also used 303 on the trim before and was pretty satisfied. However, it tends to run too, if not properly buffed out. The key in the whole process is to make sure the area is clean before application and that the product is completely buffed.
As a last resort you could try some Forever Black on your trim, but unlike the other products, this is a dye and is permanent.
