Petseal removal from fuel tank
« on: 28.12. 2011 17:48 »
Wonder if Anyone has a method for removing old Petseal from the fuel tank without destroying the paintwork ?
Mine is coming loose and has gone rubbery ?

Regards,
Steve...

That's thanks to Ethanol in the petrol... I've yet to clean my tanks out on two bikes at least, the gunge is still on bottom of tank waiting to block the tap filters at some stage in the future... *sad2*

 G'day Steve,
                  I haven't tried this one http://www.tankcareproducts.co.uk/ but have been told it works. There is also a product called TEK or TEC.
The last one I did I used a gallon of methanol left in over night. Gooey mess.
Cheers

Hi Stephen and All,
Caswell make and sell a product to remove the petseal and I have used their sealer to good effect on several tanks now
I have also used "Nitromors" (in the yellow tin) I was told the other week when I went to buy some more of it that it has been withdrawn from sale to be reformulated to make it safer!! I managed to find a couple of cans at another store
Both these products will wreck paintwork on tanks *eek*
Caswell recommend wrapping the tank wit hseveral layers of clingfilm and tinfoil after plugging the tap holes etc
I also sealed around the filler neck with duct tape and tied a cable tie round this tightly

These products break down the petseal into a kind of granuluar form, which can be washed out with water
the caswells can also be sieved and reused

Hi there. I can recommend the product supplied by Tank Care Products to remove Petseal  I have used it on 2 tanks you have to follow the instructions carefully and make sure you do not get any on the outside of the tank as it will damage the paintwork but if you are careful it is not a problem just cover the outside of the tank with plastic sheet and leave a hole around the filler neck to pour the chemical in.

Hiya,
Just waiting for the kit to arrive from Tank Care Products,
I've gone for the 4gall. kit with the Petseal remover,
so I'll let you all know how I get on!
Happy New Year to everyone. Cheers.

Hiya,
I thought I would let you know how I got on with the Tank Care Products Kit, in stages.
Part 1.
1) I carefully covered the tank with clingfilm, polythene and then, as I thought, sealed
around the filler neck with tape. The fuel tap and breather holes were plugged.
2) The Petseal remover was poured in and the tank sealed. After 3 days! it eventually
had dried out sufficiently to be tipped out in it's granulated form. After a good workout,
(shaking the tank with a handful of nuts & bolts inside) the inside surface looked clean enough to proceed to:-
3) The rust converter was then poured in & left for a few hours, then drained.
4) The tank was then rinsed out with the TP1 solution, drained and then dried out with a hot air gun.
5) I left the tank sitting on top of the tropical fish tank overnight, (this kept things over the 60 degree
temperature needed for these processes to be effective).
6) The tank was then rinsed out and drained with the TP2 solution. The fumes from this stuff are EVIL,
I wouldn't use the hot air gun, so overnight the fish tank came into play once more!
7) Back to the instructions again for the sealant application.
8) Removed the plugs after 18 Hrs.. Sealant was too soft before this, but hard enough not to sag by then.
The threads could still be cleaned easily with nail varnish remover (acetone).
The tank is now curing and after 5 days is looking pretty good.
Cheers.
Part 2.
Upside.) *smile*
           I now have an ethanol proof tank.
Downside.) *sad2*
          1) Unfortunately one or all of the chemicals used, have leached passed the seal at the filler cap and
softened the paintwork around the neck!! ( See image). Awkward to seal properly 'cos of the filler cap bracket!
          2) The wife is still not talking, ( shouldn't have done it in the front room I suppose!
Well it had to be done in the warm, didn't it?).
          3) I'm sure the fish are giving me dirty looks when I go past the tank.
Sorry if I've gone on a bit, but it might help someone about to do the same job.
Cheers.
Regards, Geoff.
