Well, I washed our 380 yesterday. The poor thing has been kicked out of its carport space by our Santa Fe and my red Ralliart takes the other spot. As 380 owners would know, leaves and dirt accumulate around the boot strut attachment areas and there are several spots that are hard to clean there. Our white 380 has had debris and dirt there for a few months and now the paint has been stained a greenish colour that does not scrub off. Has anyone had any success in cleaning this/removing the stain?

There are two things you can try with that:

The first is to clay bar the area. Might have to go over it a couple of times, but that can get a lot of things up off of the paint.

If that doesn't work, try some Goo-Gone or any orange based adhesive remover. They also work great on plant matter stains. The best part is that I have yet to find a paint job they do any sort of damage to, even after letting it set for twenty minutes.
