Dishwash liquid streak damage

[Johnny]

Dishwashing liquid was poured on the exterior of a cream white body (BMW 1986 [Chamonix paint]), so that it flowed down in rivulets, and left for 15 minutes in the sun.

The result was a slightly lighter exterior wherever the dishwashing liquid touched the body, causing lighter downward streaks that could not be removed in any obvious way (washing, buffing).

I suppose that the dishwashing liquid had a lasting degradatory chemical reaction with the coats, since it was left for a relatively long time (15m) on the paint.

In the right lighting the streaks make the otherwise beautiful paintjob look really ugly.

What can be done to safely reduce the contrast between the slightly lighter streaks and the untouched cream white body?

first off, welcome. now, how about some pictures to help us help you? what products were used when buffing?

I talked with a pro today and he said that it is the clear coat only that was tarnished.

He said that dishwashing liquid will do that, especially on a hot day.

He said that the clear coat needs to be removed and reapplied, a relatively quick fix at about $100 for the whole car.

One can see the vertical rivulet streaks especially at the bottom half of the door:

no picture. was that one hundred dollars???? what exactly is the clear he's planning on using and what kind of prepwork? i couldnt even get the clear for $100. dude, get us some pictures.

Sounds like he may just wetsand the clear that is already there, because for $100 he could not even buy the materials

Just a question. what was the soap 'poured' over the paint job for. I've never heard of that.
Normally it's mixed with water, then you use it.

I wasn't for sure what you meant by the "rivulets". Is this like the door jams or fender jams?

Somebody screwed up, because you are right, the soap should be diluted.
By rivulets I mean the streaks that rolling droplets make as they move downward.

You'd be surprised at what $100 can get you when you live in Africa =)
And I did not even mention that the shop will also glaze-coat the car, already included in the price.

I'll post pics after the car is done, but the shop only opens at the end of Jan.
Happy new year.

I wouldn't think the car would need to be repainted. Try having them wetsand and buff it first (not just buffing).
Hard to believe soap could do that much damage. Must have been a very fresh paint job or a very hot day or a both.
