I use my bike for commute and weekend. So I have to add petrol at least four times a week, sometimes 8 times. From time to time the petrol dripped on the fuel tank. 

Try paint doctor. It's a polish. 

Its going to be a staining or discolour in the clearcoat, so a good quality paint correction product with a DA polisher should take care of that easy. 

The key is 'good quality' and the right product for the job.  (the tools alone can cost $300+ and then another $200 for the products and pads, but its a good investment as you can reuse for your car etc)  Are you in Melbourne East or West?

thx for all reply. I guess commute bike should look like commute bike then. 

how far do you commute to have til fill up that often, would be cheaper to buy a house closer to work

Bahahahaha. Fuck that made me laugh :-)

Giving the content of the comment here, I think you fall better under the definition of "clown". 

I have 6 different work locations every week. 

Invest in a good sealing gas cap too and stop dribbling.  I fill up twice a week and paint is better looking than when it left the factory.

Its Xmas...we love everyone!  

I never really count the number of times I fill up in one week ( but I ride my sporty a lot ) it is white too, I could have got fuel on the paint a few times, but I'm mostly careful. & if I do spill some I wash off with water before riding off. 15 year old bike ( 16 next week ) can't see fuel stain's. I always thought the new paint they use was fuel proof? I can remember old days fuel stuffed paint if not cleaned off quick.

also today's Harley's fuel caps seal even if bike upside down
