There are various ways to do this, none are perfectly correct because there are various things to take into consideration that can change from one vehicle to the next.
The rule is to trim it away leaving the rubber exposed. The trouble with this is how far back do you trim, because trimming on the rubber leaving a little lip, actually creates more issues than wrapping over it.
trimming it back and off the rubber, can expose both the gey/black rubber and white. making it stand out much more, but at least the vinyl has a better adhesion against the paintwork.
for me, it greatly depends on the age of the van and the finish of the rubber. some are very clean and the vinyl bonds not too badly, others the adhesion is poor and requires trimming.
hard to advise because, as I say, I use different ways from one to the next.
perfect case scenario is one that will allow you to bridge the rubber but the rubber allows a decent adhesion. apply heat and rub down it firm to promote adhesion. at the very top and very bottom. just on the rubber, “if you have any” put a little dab of 3M adhesive promoter.
all this does is prevents water running down the back of the bridge. also, if you are applying vinyl panels top to bottom of the van, take the vinyl up under the gutter which also helps prevent dirty water going down the back of the bridge. this seldom happens, I’m only telling you these points because if you do as many as you can, you shouldn’t have any problems at all.
I have seen some people use primer right down the rubber. but this is messy sticky stuff at the best of time and the last thing you want is the wrap to be removed and the rubber is caked in the adhesive.
some rubbers have a nice gloss coating which WILL take vinyl. but they sit a bit proud and its sometimes best to NOT bridge but apply up to it and over. once applied neat, using a new blade, slit down each side. that way if there is flex and movement or anything gets down the back, the strip of vinyl covering it can be peeled away easy at a later stage, if required withing affecting the original job.

Yep, exactly what robert said 😀
For me if its normal vinyl or print on a van i always cut and remove, leaving the rubber on show.
Wraps however i feel its best to cover, even if the adhesion isnt great or even creates a “bubble” non tack line. This is normally not noticed by anyone but a white rubber line on a blue wrap for example sticks out way too much. 3m primer is always an option.

Thank you gents. Will go down this route.:

I have just realised this van looks like a van we did a part wrap on early last year.
If you look at the area I have indicated with red arrows below. This WILL cause you problems in a couple of ways. It has one of those raised joins right in the recess of the van. I forget exactly how we addressed this but from memory, we had to feed/fold into, cut and overlay a part. very hard to explain, but thought I would make you aware of it.
I would advise printing an extra splice just down this area a few inches wide by the depth for overlaying purposes once you cut it. I say that so you have a colour matched spare bit to use.
