Hey CarolinaJoe,

Sorry to hear about the problems. I haven't had this issue. I work almost exclusively on black cars. Last week I did 3 black cars, this weekend I got 2 more.

I'm using M80, M83, M21, #7 without any spotting issues. Maybe it's just California.

I wish they were just water spots, but they aren't.
The Fiero is a new paint job and the pics I showed are of the Cadi. Both cars are garage kept and are not outside when the sprinklers are on. Both cars were done with the Rotary first, well the Cadi only half as the Rotary was smoking.(Garbage)
I will give a short of what is happening.
The spots come out, but totally gone after detail.
Shortly after 12 hours when using the #80, 21 & NXT the little spots come back.
Last time used the #21 and then NXT, took alittle longer to come back but they are there again 5-7 days.
I do appreciate your input RedSoxRacer atleast we are throwing some ideas around. Whats weird is how can this be happening to 3 vehicles 04 Trailblazer (Dark Grey), 01 Eldorado (Black) and 86 Fiero (Black).

Quite strange indeed.

They do look exactly like water spots.

So far, everything you've said about their behavior sounds like a perfect description of water spot etching/staining.

It's not that they're coming back, they aren't leaving in the first place. The fresh application of product reduces their visibility but they're still there and are just reappearing.

Etching/staining isn't just on the surface, it goes down into the bulk of the coating. Hopefully it doesn't go too deep. It's possible for it to go all the way through depending on how concentrated the chemicals were in the water, how long they sat on the surface and how strong the sun was baking them into the finish but with any luck they're only in the very topmost portion of the coating.

I've seen spots that were completely removed with a light cleaner/polish by hand and others that were barely touched by heavy cut cleaner and a rotary buffer.

I'd recommend experimenting with very small test spots, maybe 3"x3" or smaller, but no bigger than 6"x6". Study the pattern of the spots very carefully before and after trying different techniques, preferably with a magnifier, to see how much progress any given technique gives you.

Study the effects before topping it with protection (NXT, #21 or whatever), it's the condition of the paint itself, as left by the cleaner, cleaner/polish or compound that's critical. Those products still have oils that can reduce visibility of defects so it's probably a good idea to wipe the finish with something to remove them before inspecting, a solvent type bug&tar cleaner, alcohol or NXT glass cleaner.
