Paint Damage

[pjh56]

My partner had their MG resprayed two years ago, two part (paint then lacquer). The car is always garaged but recently snow has blown in the small gaps around the door. Snow settled on the boot for a day and has caused this damage. My everyday car is outside, covered in snow for two weeks and has no damage.
Does anyone know what has caused this, is it temperature or moisture?

It first looks like wax spots (dishes) in the surface paint finish, but some of it looks like ( micro blistering) which is when a panel is sprayed in damp conditions,has not fully dried out from wet flatting, or water in the airline etc etc. If its any of these then its the fault of the bodyshop and should be resprayed FOC. Might be too late now.
It will not have been caused by the snow. Cold conditions can show up body repairs which disappear in the summer when its warmer.
To be honest there are so many possibilities with resprays that its impossible to be accurate without knowning the state of the paint prior to the respray, if the original paint was simply 'keyed' and blown over, or bare metalled. Type of paint used, cheap quality paint can cause surface reaction in underlying surfaces, especially on 'clear over base ' resprays, as you are trapping 2K primer over 2K laquer over celly basecoat. It might even be waterbased basecoat, which has not dried correctly then covered with a 2k laquer. It goes on and on.
Word of caution for those with recent resprays , do not use a car cover on it for at least 6 months especially if left outside.

Thank you for your quick reply Jonathon. It came to light the respray was not top quality on the first polish, there are pits where the lacquer has not taken. I will have to take it to a garage with a better reputation for repair. The annoying factor is it was not a cheap respray that was paid for, over £4k. They must have known the car was kept in a garage and would not show any problems straight away. In the 9 years prior to the respray none of the paintwork showed damage, even when kept outside for 2 years.
If it is wax spots can they be remedied?

If its wax or micro blistering then you need to ideally bare metal the car. wax can be contaminant or silicon, if the latter then this will need sorting properly.
You can flat back wax spots but need to be wary of the thickness of paint that you then respray the car with, too much paint will cause cracking.
When you re commission the job, ask the bodyshop for their opinion of your current problem and how they suggest its remedied try and see examples of all stages of paint prep in their workshops and maybe even ask for past customers of a few years ago and view their cars.

Many thanks for your advice Jonathon, I contacted the garage who did the respray and they are looking at it today, so hopefully i'll know the outcome later.

The garage has agreed to respray the car FOC.

Too right

Thanks Alan
I must admit as a novice when i'm up against the industry I tend to lose, but this time i'm pretty pleased with myself. It's amazing what a bit of information from people in the know can do.
I'm just really grateful.

thats a great result well done

Well done, companies are often only too happy to put right 'mistakes' or errors if they are reputable, I'm impressed
