how easy/hard is it?

if you dont recommend doing it yourself, any recs in the San Antonio area, even New Braunfels

I did on my Tahoe using Chemical Guys prescribed process + materials. Didn't help that I did it on a huge car, but it's some work that was gratifying for me. I maintain now with the HydroSlick product and it's held up really well for 2+ years.

Yes, I've done it. Used both Geyon Mohs Evo plus Skin and Pan the Organizer 8 year coating. Prefer Pans. If you're a do it yourselfer you'll be fine.

I priced out paying someone and for a mid sized sub it would've been $1400. The coating is anywhere from $50-$150 and I had all other supplies.

I did my new Audi last Feb with Crystal Serum Light.

~$80, plus a little more for good shop towels.

Took a couple of hours -- about the same as a quality wax job. Not much more difficult. My car was new so the prep was easier. Otherwise, you want a thorough detail and clay bar, and then use the ceramic.

Still beads water extremely well, and looks great.

I've done a few. Geyon Can Coat was the easiest by far
