No one is suggesting using it regulary, the intention is to remove the issue at source, which I believe to be oils an residue in the rubber. I could however be wrong but it certaily looked like that to me. I agree with you on the comment regarding the degreasing properties removing the issue but the general properties of Prep I believe will also be helping.electric said:Gyeon Prep is a solvent based cleaner which I would not use regularly on my car. Being basically an alcohol solution over use could be detrimental to the rubber window seals. It's degreasing properties are probably what is removing the mottling effect.
Good evening,Just checked mine. Mottled markings back again. Will contact the dealership again.
Mine was exactly the same. 2021 S-line.New to forum and have already posted this question elsewhere on the forum......wrong place, I suspect.
My new Q2 has very odd mottled grey/black window seals. I first thought it was pattern! But it's clearly not as it's very irregular and doesn't look good. Has anyone else experienced this? my A1 didn't have this issue.
