Best I have ever found is G Techniq C2V3...I use it as a drying aid. I wash the car, after final rinse blow excess water off with battery leaf blower then spray 1 or 2 sprays per panel and wipe dry. The stuff is on the expensive side ( but so is your car). I have tried Gyeon Q2M cure but in by experience it took a bit more wiping to get a streak free finish than C2V3...but still overall very good. Avoid anything with "graphene" on the label, it is junk that appeals to the Walmart/autozone customers for some reason.

 

I have a G Techniq coating. I use the G Techniq Quick Detailer after a wash and dry, after every wash on the front and mirrors and every other wash for the rest of the care.

 

I used to do this in my apartment building garage, but had to have portable lighting, etc.. My neighbors thought I was nuts (in a good way, I think), but would always stop to chat with me about what I was doing.

A few years ago I renovated a 100 year old house in Brooklyn and part of it was fitting out a garage for my car and detailing / other projects. It included all of the detailing essentials, including wall-mounted pressure washer, high output lighting, etc. I've posted some shots of the full project in other threads here in RL (it was a major undertaking with a large structural element), but here is a couple of "after" shots of my work area:

 

Adam's - it's the best and doesn't leave streaks. it also smells so good that I find myself using it more and spraying quite liberally, so I buy it by the gallon

For a long time I did ONR washes in the garage as they didn’t lead to water everywhere and nobody would every question it. Eventually I became close enough with my super that they let me use a hose setup of theirs in the corner of the garage to do full washes. I definitely didn’t have a pressure washer setup then.

 

Yep, did ONR washes for a decade using a few gallons of water in a bucket. Worked great
