I can vouch for Vu being more than willing to help out even when there's nothing in it for him. If I held onto my car, it would've been getting resprayed there.
I've heard a few stories of people not being 100% satisfied with the work, but I've also heard they're more often than not willing to sort out any issues later on.
At the end of the day they offer more affordable resprays than 90% of other shops. If you want perfection, pay for it.
