Car cover & my resulting paint work
Discussion
Due to financial restraints, my car has spent the last 12 months outside, but under it's waterproof/breathable cover.... However 
On removing the cover today, I noticed some condensation on a rear wing, the boot & a bit of the roof.
On wiping this away, it's left a white/Grey coating which I hope is 'on', rather than instead of the paint.
It basically looks like dried polish, before you rub it off.
I haven't attempted anything on it yet, that will follow. But i was wondering if anyone had suffered the same ?

I'm guessing it could be mould, but sort of expected it to look Black, rather than White.
Cover looks fine on the inside... It's having a day on the clothesline though
Let the paintwork breath for a few days and then see if you can polish the marks out.Cover looks fine on the inside... It's having a day on the clothesline though
Having been a sprayer for 30 odd years I have always advised that covers on paintwork should not be used.
My Chim lives outside and I have a cover but only for the roof and windows in the winter.

Thanks..... Been having a mooch about on the internet....dangerous....and found this.

"Over the years of the use of transit wrap by vehicle manufacturers, there have been thousands of hoods, tops, fenders repainted due to moisture entrapment showing after the removal of the plastic transit wrap.
In most, and I mean "MOST" cases, the repainting was not necessary.
But the sub contractors at the ports sure liked the additional income.
Here is what they now do when this concern is observed.
1. Wipe affected area with rubbing alcohol (70, 90% what ever) and make sure the area is "wet" with the alcohol.
2. Alcohol (IPA only in this case) is a "drying agent" which is why it is used.
3. While wet, using a heat gun or even a hair dryer,start evenly heating the affected area, but do not allow the skin temperature of the painted surface to exceed 175 F.
4. Move the heat and air source, evenly over the affected area, starting at one edge, working your way across the area.
5. Observe if the "cloud" is going away.
6. A second application and heating may be required.
If this does not remove the entrapped moisture from the clear, and you should wait a couple of hot sunny days to make sure, then refinishing is the only option.
This process has been done on thousands of new vehicles at ports across the world, as a less expensive method to relieve entrapped moisture, so it's nothing new"
As Malcolm mentioned above, the car can have a few days in the sun, hopefully. And the expensive car cover can have a permanent visit to the tip.In most, and I mean "MOST" cases, the repainting was not necessary.

When I first discovered it, I thought I'd let the valeter have a pop at it, but thinking about it, I'm guessing the polish/wax will just seal the condensation in.
Doesn't look like we're going to be having much sun from now on in, so I'm wondering whether it may benefit from going somewhere ? Like under the heat lamps of a paint shop.

Just google images for milky damp patch. What could go wrong?Sounds like the heat gun idea is worth a try. It works for furniture that gets moisture under the varnish (the procedure there is to make a tiny hole in the varnish with a pin and heat it with a hairdryer).
Bit of an update.....
Car hasn't really got much better on it's own, I'm guessing it's not getting hot enough.
However, I've finally got round to attacking it with a hair dryer today and I'm pleased to say, the car is miraculously changing from White, back to Blue
It's going to be a time consuming exercise and I'm sort of worried that I'll miss a bit, so I'm after advice as to somewhere nice & hot, to leave the car... I'm guessing a paint shop with heat lamps ? I presume an oven would be too hot ?
Once back to Blue, I'm going to coat the thing in wax to hopefully stop a recurrence.
