I noticed this spot while quickly washing the new Jetta the other day. At first I thought it was tree sap, which would be odd on a new car. I used bug and tar remover which is what I usually use on sap and it didn't help, then I moved up to NuFinish and then to Meguiars compound. Nothing has taken it off. I am thinking it is some contaminant under the clear. The rest of the paint looks fine. I am not interested in having it repainted, at most I may mention it to the dealer when we go in for the first time to have documented. Have any of you seen something like this before on factory paint?
