Scooterotica

Hi just got my ts1 back from read speed , and found my fuel tap furred up , was told that the ethanol in the petrol will eventually start breaking down the fibreglass and will continue to fur up my tank ,,
I was told there is a product to put in my tank to protect against this , does anyone know what it is and where I can get some
Thanks

maybe this http://www.frost.co.uk/ethomix-additive.html. but read up about it on Frost`s website to make sure it`s ok with Fibre glass .
