back when I was riding my Harley, in 2013-14, I found I often had to be aware of residual fuel in the nozzle that would spill on my fuel tank. That lovely paint!
So I developed the habit of placing a gas towel over the area. Back then, it was a problem. Maybe not so much now? If fuel recovery is anything like the freon recovery regulations...
And, for those who spill gas on paint...JUST LET IT DRY, DON'T WIPE IT!
