I honestly wouldn't go the hydrographic route.... I have seen many, and I mean many times where it just peels right off. I have tons of customers ask if I can repair or touch-up the spot where it has peeled off. It's all in the degreasing when laying down water born graphics. If you are not there while they are degreasing it, then you can't know if it was done right. I know...... I have a buddy that makes luggage/hunting racks for SUV's and such and been there many times.
Multicam is in my opinion the most labor intensive camo patterns to do.
I paint it, but I use duracoat and do not use their 'camo pak', I instead use a custom blend of their colors to perfectly match actual clothing/gear.
Btw.... Sorry, not taking any orders right now, I'm all back up for a few months and have to get caught up before accepting any more work.
