Some kind of tar on floor pan/chassis...

PS. I wanted to mention that I live by the following motto:
"One day, I will save someone's life with WD40!"

I ALWAYS have a small can of WD40 with me, especially when I ride with my motorcycle. Never leave without it! Did you know how well it works getting bug-splats off paintwork!?

I'm going to look into liquid C02 next time. Maybe that will do the trick. Give it a quick shot, then just break the crap off with a hammer.
