Tank sealer
« on: 31.03. 2018 11:30 »
Has anyone found a proven, long term, ethanol proof tank sealer. ?
There seem to be a lot of sealers out there but, there are a few stories about sealer failing after a short period.

I used POR15, not to seal a leak but to deal with rust. It's been solid now for six years: https://goo.gl/LE9DD8. I'm in the UK; we may not have as much ethanol as other places.

Thanks GB. That is what I want it for.
My tank is pretty much rust free and I would like it to stay that way.

I'm sure you are about to be advised not to do what I did. Cleaning the rust out is supposed to be quite easy, (as long as you have some nails and screws a cement mixer and an old duvet).

Was the £49.99 kit enough for your tank (4 gall) ?

Yes, it was. Shop around; I'm sure I've seen that kit cheaper.

Tip: When I needed to thoroughly dry the tank after degreasing I wedged the hose from our vacuum cleaner in the filler hole using rags and left it sucking air through from the tap holes for half an hour.  ;)

Hi,
 I used them all over the years ,starting with Kreem,Caswell, Tank Care Products and POR15.
POR 15 is the easiest to use and does not require a silly temperature of 55C to flow.(Tank Care Stuff)
 As well , you get some patching mat to cover holes you might have at the bottom of your tank, works a treat!

I've ordered a kit, two 3/8 BSP plugs and 1/4 & 3/8 BSP taps to clean out the threads.
Do I need to protect the paintwork ?

Take great care to not get any of that stuff on anything that you don't want it on. It sticks like shyte!

I used Tapox on my A7SS which gave an excellent covering, so far durable.

The main difficulty I had was ventilating the tank to get the sealant solvent out and prevent runs.

I used a small CPU fan off an old PC motherboard in the finish, left it running half covering the filler opening for a week and all was well.
1961 A10SR, spent a fortune at SRM
1961 A7SS, finally the right green
2011 New addition 1937 Empire Star, twin port, high pipes. Turned out to be the most unreliable bike I have handled.
2017 finally found the liner/barrel were flexing and causing all the overheating/nipping up. Early B33 barrel fitted and it's reliable at last!

I was thinking about using the vacuum cleaner like GB and my late wife's hair dryer to warm the tank from the outside.

You got me worrying about whether I should worry about this now, so I have gone and looked at the A7 tank and just a few small reddish patches, not even sure its rust. So is there any point in lining a ‘good’ tank that has not rusted whilst in use for the last 5 years.
Dam looked in Norton tank and its got a ‘nice’ layer of what is defiantly rust so regardless of reply one to do I suppose.

NO  *ex*

Electrolysis is the easiest way to clean the other tank and then preserve the insides with a coat of oil if not in use

Its in use but I had not looked inside like that before.
Electrolysis, electric in and around a petrol tank (even empty and cleaned) one little spark and *warn* *problem* *sad*

Did a search MikeB says he did it but every article I can see talks about immersing the object in a container. Now the outside paint is good on the tank so I dont really want to do that. Could I just put the liquid inside then connect the tank to a the negative side of a battery and carefully put a positive electrode into the liquid in the tank without touching the sides.

Yes, That is how I did the tanks
I made a wooden bung to act as an insulator, driled a hole through it for a push fit to a bent metal rod
The only thing is that you need to remove the bung and clean the rust off it fairly often at the start
Connect a headlamp bulb and fuse in series with the circuit to keep the current limited *bright idea*
This also protects against short circuits *warn*
