It all depends on who does it and the material used. when you say vinyl wrap do you mean vinyl fabric or the plastic film?
The boomerang would be challenging to hydro dip because of it's shape. If you want the carbon fiber to come out looking uniform and not stretched at all it is going to have to be done by someone that knows what they are doing. That usually has a higher cost attached to it.
Here is an example of stretching, and just an all around bad dip.
This is a really good job. Notice how there is little to no wavy gravy going on and the pattern is constant.
I looked for some examples for vinyl wrapping (old school) and I kept on coming up with stickers and the vinyl film examples.
Old school is using a fabric backed vinyl and contact glue is used to affix the vinyl to whatever it is that is wanting to be covered. If you look at the arm rest in the Solstice this is vinyl wrapped but not using the vinyl film.
The finished product is very different. The film has no depth to it. It is 2 dimensional. The fabric backed vinyl is thicker, more durable, doesn't scratch and because it is thicker the carbon fiber look to it has depth and looks like it is really woven. The only downside of the fabric backed is the sheen, It is going to be matte until a product like Armor All (this is an example don't even use this specific brand) Is applied to it. The gloss that is gotten is not going to stay and it will dull over time.
hydro dipping is paint, The boomerang is also going to need to be clear coated. Hydro dipping it's self is going to give you a 2 dimensional appearance. depth can be added based on how thick the clear coat is. The thicker it is the deeper it is going to appear. This can be scratched as well but it can be repaired by using rubbing compounds and sanding if the scratch is not too deep.
Vinyl film you will have to get it redone to fix any scratches.
Most durable is old school vinyl wrap. Middle of the road price.
second is hydro dip only if there is a really thick clear coat, other wise it has the same durability as vinyl film. To get done correctly is going to cost. This is the most expensive when done properly.
and on the bottom is vinyl film. Cheapest
