Tank sealant removal
« on: 24 January, 2020, 01:50:56 PM »
If anybody has an older bike that has had tank sealant from back in the days before ethanol which turns the likes of Petseal into a slimy gunge bunging up carbs & worse if it gets through to valves. I have recently cleaned this sealant out of my old Ariel FH tank using Dichloromethane, 23/4L off ebay.

I wrapped the tank in 3 miles of cling film, fitted a ball valve to the outlet, poured a couple of Litres of the liquid into the tank & closed the filler neck off with a cork. A few days later with no liquid left sloshing, I removed the cork & all the Petseal came out like mulch, a shovelful of it. Swilled the tank out with diesel, all gone.

I gave it another small dose just to be sure but there was no need, job was done.

SO,, i'm assuming the sealant was put in for a leak. How did you fix it.

Pictures?

Nah m8, there was no leak but being a very old tank '58, I thought it a good idea at the time. We'd never heard of Ethanol or it's effects back then.

I have pic of the tank covered in the 3 miles of clingfilm to try & protect the paint from the Dichloromethane & the shovelful of Petseal mulch that came out of the tank after a few days. I did the job in me wheelbarrow in case I had an accident with it.

Probably  :451:  But I want to know more about this bike!    Pictures? Story?   Have you had it long?

Aye m8, had it longer than I had any of me wives. Bought it for 2 back in 1969, must be worth near a fiver now with inflation. Chucked all the heavy stuff in the bin and fitted BSA super rocket h/c pistons, spitfire cams, cowhorn bars, ally guards & banana seat, as we would back then. Took it off the road early 90's to fettle it a bit, ended up with it in every piece. I painted the frame in the garage then put it next to the radiator in the dining room to dry being winter. Just kept adding bits as I fettled them. Couldn't locate a nacelle so I cobbled up some brackets to hold the headlamp 'til I find one.

I made the handlebars from Stainless steel tubing, bent them to shape using a borrowed Electricians conduit bender, that wasn't easy to get uniform both ends & hard work physically.

It's been sat there sulking 'cos I'd put that Petseal in the tank & so many people told me I wouldn't be able to get it out & need to get a new tank. Well it's out now, so mebbe I'll get it on the road sometime in the future, if I can still kick it over. I had welded & pickled the tank before putting that dreaded Petseal in so hopefully it won't leak.

See pic, it's similar colour scheme to Buddy Holly's Cyclone but not quite so original.

thought that might be the case given your earlier post  :008:
are the tank & red panels original condition or have you had them redone?

I painted it with rattle cans. It looks better in pics. The pin striping was tricky, I went on the waggon for a few days for that.  :031:

I might re-do the paint job.
