Hi Roy. This sure sounds like rust from the other side of the panel. I'm wondering if the folks who made the prior repair removed the wheel well liner and took car of things on the inside. If they didn't, no amount of repair from the outside will permanently fix the damage.
If you're like me and want to keep your Crosstour "forever" then making this repair properly is well worth the expense. Let us know how you make out.
