I have been installing paint protection film (clear bra) for a while now and have been using Ventureshield for the past few years with great luck.
Over the past 6 weeks, I have been trying out the Xpel Ultimate with self-healing properties and have to say that the film blows away Ventureshield in every aspect. It is a little tougher to install, but the gloss and clarity is the best I've seen and there is literally no orange peel.
We do mostly custom installs covering complete hoods, complete fenders & bumpers and it is almost impossible to see once installed. Of course it all depends on how good the installer is too.
