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.) 
I now have an ethanol proof tank.
Downside.) 
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.
