I fell for that one too-what a mess. But you know, when you're desperate, you'll try about anything. Listen to the Floridians, they've been dealing with these little beauties for years & have discovered many ways to clean up the mess. Nothing beats experience.
Thanks for all the ideas; glad that there is more than one way to skin bug guts.
Mr. Clean Magic Eraser is fantastic. I have used them for six years and it hasn't hurt the finish on truck or rig.
I would bet that it has, but it may take a long time to notice. You wouldn't use a polishing compound on your car/truck every time you come back from a trip. Melamine foam sponges are effectively very very fine sandpaper on your finish.
