Salt in my Chips?

[Glasseye]

Did a repair on a Range Rover yesterday. Half inch bullseye, dried it out, nice and clear, look good for a repair. Performed the repair and on completion, before curing, I noticed this milky white hue just below the impact point of the damage, crescent shaped. I thought at first it was water reacting with the PVB turning it milky, but on closer inspection the stain was not near the PVB. Tried to remove it with no success, but it was not a big stain and the rest of the repaired area was good. This puzzled me and, after a great deal of thought, the only explanation I can think of is that the snowy and icy roads around here have been treated with rock salt turning all the cars white with salt. The moisture trapped inside the repair must have had salt residue dissolved in it and it has stained the glass inside. Anyone else come across this?

We have road salt during winter too (both in Nederland as well as the US-Midwest).

From what you describe, to me, it looks like it was a coated windscreen. Range Rover is a top brand, they may fit those screens (don't know this for a fact though). Are you sure it was not near the PVB?

We were told, many years ago, during the training, that road salt indeed was one negative factor -this I still remember clearly.
Never experienced what you just described myself though.

I work in salty conditions 4 to 5 months every year. I have never encountered a problem like you had with a stain in the damage just from salt. I think salt is salt all over the world, but there could be a difference. I would consider another possible like what the salt ate off the road and threw up on this windshield. Salt will clean a lot of debris from the road that may have been on there for a while.

There is an old used car trick put a drop of transmission fluid on a chip the day before auction they dissapear but weeks later you have a white stain inside the break maybe this was the problem
