A couple of clarifications:
1. No odor of gasoline in the garage.
2. Odor occurs only when cargo hatch lid open, dissapates quickly.
3. There was a small overspill on a hot day a few years ago. Cleaned with cat litter and Dawn detergent, some may have spilled into hull and I didn't clean it well.
4. I'm aware of gasoline vapor danger, ergo my post here.
5. Will take care to clean area best as possible.
The "odor" level, is about similar to standing next to a lawnmower. It's not like overwhelmingly strong, more like a suggestion.
Thanks for your advice and I WILL have it addressed.
