I hate to tell you this, but NOTHING, will protect paint when acid rain is present! Not #20, not Zaino... The ONLY thing that will is a car cover or 3M Paint Protection Film (Armorglove/Xpel etc). A garage also works well.... Sorry had to say it.

Being the car is black, when it is out in any sun, the water dropplets turn into maginifying glass effect, and the evaporation of the water leaves the acid much quicker than lighter colored car finishes. Your best advise is to find shelter for this auto if at all possible to minimize it's subjectivity to acid rain. A car cover may be your answer if you cannot park in a garage. The other thing is to clean the finish right away with a good car detergent as most have a balanced PH and can help offset the acid content when you wash. Actually, just adding more clean water will reduce the acid.

I remember #20 years ago when I had Megs detail line: Acid Rain Correction Cream,(smells like Big Red Gum) Clearcoat Conditioner etc and had it analyzed. I really didn't want to use it as it seem to have quite a bit of solvents in it, I have to get the reports if I can still find them. I tried it on a test hood laying around and found it streaked if I did not act quickly. The streaking was from the solvents, and it was a pain trying to figure out why until I got the results. Did protect well, but I found at that time it was easier for me just to use #26 wax on cars and just freshen them up as needed.

I'm not knocking #20, but there are more modern products out there for todays paint. You may want to research this a bit more and try something that will be for that type of finish. Remember paints today are mostly waterborne and lead free. To my knowledge, #20 is still the same formula years ago the last time I checked.

As you can see I use Zaino on my Lexus, but I garage this car 24/7. I like the way it looks as my neighbor said it looks as if the paint is fluid. I just touch-up with Z6 quite often to keep any dust off of it, if it's a lot of dust, or feels gritty, I wash with Z7 then Z6 the car after.

Whatever works for you, that's great! Just remember nothing will protect a finish from acids. It's getting to it in time B4 damage can occur.
