I checked with a local hydro-imaging place, and they're wanting A LOT of money for this. I had considered getting some pieces carbon-fibered (like Roy did), but based on their prices, decided against it.
I just re-checked their site, and the prices have come down - drastically. I saw where they would cover a set of mirrors (I'm assuming truck mirrors) for about $70 the pair... truck fender flares $175 for all four. Basically, small items around $25, medium items around $75, and large items $100 and up - call if it's something crazy like a set of motorcycle tins.
Not horrible, but I'm still not interested - I have my own carbon fiber vinyl to work with now.
As an airbrusher, I can honestly say that hydro-imaging will not replace a good artist. I see both techniques working together and having their own place in the customizing biz. I would not want to attempt to make a big piece with a repetitive pattern (like carbon fiber), because it would get inconsistent the longer the project rolls on. Just as I would not want to try a truly custom graphic theme with the hydro-imaging, simply for getting the graphic lined up with the piece would seem like a royal PITA to me.
