Left wet car in garage after rain, out of town for 17 days

I never said it did ….I was just adding that the spots that I’ve always had trouble with is when the car gets spotted by sprinklers distributing lawn care products…

I'm confused too. How do sprinklers distribute lawn chemicals? Sprinkler systems distributing lawn chemicals is a new one for me.

To the OP... enjoy your 2 weeks away and forget about the water spots. Rain water is typically not a problem for destructive spotting. The spotting left from rain water is typically the result of whatever dirt was on the car when it rained and can be removed easily.

Sprinklers (or any tap water) that has a high TDS content is where you can run into issues.

Unless you are dealing with acid rain, I wouldn't worry

Sprinklers can distribute reclaimed water and that can be destructive to paint. I personally avoid sprinklers as much as I can.

There are fertilizer injectors for sprinkler systems. They are usually used with drip line irrigation but they do make injectors for sprinkler systems too. However, I’d say those are fairly rare in the real world.

Unfortunately for me and my car is she lives outside in a condo complex. I made the mistake once parking next to a sprinkler. Never again!

Don't know where you live, but that's so rare in the real world.

I believe HD sells systems that integrate fertilizers into sprinkler systems

I have had water spotting from rain so bad they needed to be wet sanded, and it was from maybe 2 weeks there. So hopefully yours aren't that bad where a regular polish / compound will remove them. I have been around nursery and irrigation for about 30 yrs and I must say that I have yet to come across any chemical injection for lawns, and seriously doubt there are any for golf courses. Now as previous posters have stated some nurseries do chemical Injection along with places like orange groves regular use injection for their liquid fertilizer.

look up fertigator and or fertigation. Despite posters not knowing about it, they do exist. Multitude of companies offering such systems,

[luckydawg]

fertigation is what I was referring to with the orange groves
If its used in lawns now it is SUPER uncommon- maybe borderline rare
