At the weekend, my tank started to leak around the tap. Over 24 hours stood in the garage it lost about 3 or 4 litres. Very smelly and a bl00dy nuisance. What has made it more of a disaster is that whatever this stuff contains. It has converted the petrol into something that Nitromors would be proud of.
It has taken the paint straight off the tank (commercial two-pack) and even turned the powder coat on the flywheel cover into a soft mush. In my experience, powder coat is nigh-on indestructible and yet a tiny quantity of this stuff dissolved in several litres of petrol (three times - it was my third tankfull) has turned it into paint stripper. Now I'm no chemist and I've no scientific evidence but when the properties of the fuel are so altered that they can strip paint (even powder coat), I wonder what the hell it's doing to my engine internals, especially any seals etc.
Now I've got to remove the s0dding tank, get another one, get it painted and then put it back again
(Edit: Just to be clear, the leak had nothing to do with the sealer, that was my own silly fault. Damned dodgy about the paint being stripped though)
.. all mines powder coated and after my petrol spillage that ruined my graphics there where no change in the powder coating although not the amount or timescale yours will have endured, The only time ive had a problem is if ive drilled something as the heat from the drill bit re heats the powder coat and melts it...Hope you get it sorted soon mate...chin up.
