I was looking at having mine hydro dipped, but think I am going to try this first. Love the 3m product and looks simple enough even I should be able to do it
Vinyl in my opinion will be more durable, plus i like the texture it has. If you accidently scratch something thats been hydrodipped with your keyes or something sharp, that stuff comes right off and you're stuck with a damaged piece that needs to be re-dipped. With vinyl, it's replaceable and not permanent.
My only complaint with it is if you don't use or apply the 3m tape primer correctly on something that has round edges, it will start to bubble the first few hot summer days. Mine did in a few places on the edges, but it's nothing that can't be fixed.
