I know how to correct the paint, but asking for best way to prevent after rain without having to wash the entire car after each rain.
Thanks and welcome any advice!
waterless wash for me

Beading is for light colored cars.
souveran sheets well the first week lol

Rest assured, its totally safe and Opti-Coat Pro and Gloss Coat safe.
Process for removal:
Ferrex, allow to dwell for a minute
Hose off
Spray MDR, gently spread with a foam applicator one section at a time, allow 5-10 minutes to dwell (disregard the 30 seconds the label says) and hose off
Spray wheel acid, spread gently with foam applicator one section at a time, allow 1 minute to dwell without allowing acid to dry, hose off
Spotless finish guaranteed!
The Valuguard ABC decontamination system which is a very thorough system, has acid as one of its stages. The other thing I always suggest and is my first go-to is white vingegar, which is a mild acid itself.

CarPro Spotless as others have mentioned and Gyeon Water Spot. Both are OK if the spots are recent - before etching.
Gyeon will degrade some of the LSP in my experience, but not the coating. So, if you have a sealant or wax on top of your coating, you may want to reapply. Hard to tell sometimes unless your coating is "grabby" as to whether the sealant or wax is degraded.
On the other hand, someone recently posted that it really takes a good polish to remove a LSP, so consider that as well.
Perfection is attained by slow degrees; it requires the hand of time. (Voltaire)

Rain water is free of minerals (may have acid rain particles) so what you have is surface contamination.
Best way to prevent is wash often and seal or coat.
I usually can just water spray and dry and no spots.

Hi Nicholas, can you elaborate on this?

Re: After Rain - Prevent Water Spots
Hi, I'm new to this having just got a black car. My neighbour is having a new extension and brick dust is everywhere. Last week it rained on my freshly covered brick dusted car and it sat for three days without moving. I've just washed it and circular marks are all over the bonnet and roof, presumably from the dust and rain. It's not that serious, no one would notice them but me, but will these disappear after time or should I tackle them somehow? Many thanks.

Cement has lime and other minerals in it. I would not let it sit, use the least aggressive method to remove the spots.

You don't have to wash the car after each rain but you can't wait 2 weeks either. I wash mine 1x a week, I never do anything after it rains I dont get water spots because i dont leave it long enough I guess. You should at least be able to do a waterless wash before 2 weeks?

Nothing is "sitting" as such, it's very light rain drop marks after I've washed it. After a read through several forums I'm thinking of trying some vinegar. Just a spray and wipe to see if it works. But this building work is going to last 4 months...so I've just got to hope for a dry or wet summer, but not both.
