Ceramic sealant

I started using Griot's ceramic spray coating last year on my 20 black RAM, wife's 12 white Grand Cherokee and my 11 black Street Glide. I prep them all first by washing with a soap to remove waxes (dawn), then surface prep (bug/tar, clay bar, compound, etc) as needed but usually in spring. The black really pops and the paint looks deep. I am impressed with how long the ceramic coat lasts and I touch it up every 3 months or so. When you wash it in between, it looks like I just detailed it and that includes getting through hunting season and salty winters. It definitely helps protect the paint IMO.
