Over the years I've found that unless whatever it is you're printing is going to be subject to extreme violence, like being on a vehicle door that's used for crashing through thorn bush, or you need that additional thickness for some particular application situation, liquid laminate performs at least as well, if not better, than a vinyl laminate. I've had prints coated with liquid laminate in the sun for over 10 years with little if any appreciable deterioration. I've had liquid laminated printed panels on the hood of my truck for going on five years. Subjected to all manner of sun, all manner of weather, and countless voyages through the car wash, they appear no different today than the day they were applied.
The same cannot be said for prints laminated with either Oracal 210 or 290. With those prints I've had a non-trivial number of them that have suffered the brown death to one degree or another after but a few years.
These days, more and more I reach for the liquid laminate in lieu of the vinyl variety.
