resin in tank falling apart

Go here.    http://www.tankcareproducts.co.uk/      Scroll right down to sealant removers.

I have used this stuff to get failing tank sealer out of two tanks.........neither of them needed sealing in the first place.

Tank sealer is ghastly stuff, to be used as a last resort and only if it's really needed.

If the ethanol in the petrol is breaking down the sealant, them meths would do the job, basically, this is ethanol with 5% methanol added to stop folk drinking it and to avoid the alcohol duty.
THF is pretty nasty and may now be a banned substance (possible carcinogen).

so far I have tried petrol and then Acetone noting. i would leave with just petrol and use but the liner is about 1 inch thick at the bottom and it keeps stopping the fuel exiting. i have ordered some MEK (read on the other forum this will shift anyrhing) fingers crossed.
so far spent £60 may have got another tank for that  ;D

I have just re done a 1959 BSA tank, I sealed it with petseal back in 1985 and the ethenol has broken it down and it has sprung a small leak.
I have used a product called Slosh, recommended by VMCC members.
I also got a tin of cleaner that removed the petseal very successfully.
I'm waiting to get the tank painted before i fill with petrol and test for ethenol resistance but only time will tell if it's as good as people say.

Hi,
     MEK is a solvent type cleaner for preparing industrial plastic pipe for "glueing" fittings on, both the glue and MEK dissolve the plastic surface, which makes it a very efficient cleaner of most things, including paint brushes, extreme care should be taken not to get any onto your person as it is also a powerful degreaser, if MEK won't shift it, I don't know what will, Just bear in mind it is an industrial product and treat accordingly.----Ken
