Fuel tank floaters

[ahebron]

When I bought my 1150 GS the bike arrived with a dented tank.
I got the dent fixed and a lovely job they did of it.
Go forward a number of years and when I looked into my tank I saw floating in the fuel long strips of paint.
Obviously what happened was they repaired the dented outside but did not treat the inside of the tank and the paint has slowly but gradually peeled off the inside of the tank.
So now I am faced with the task of dealing with this.
First thing I thought of was paint stripper but as the outside of the tank is still in very good condition I do not really like the idea of getting stripper on the paint.
Unfortunately that was my only thought about this.
Does anyone else have any ideas on how to fix this problem.

Thanks
Adrian

Traditionally a large handful of nuts and washers then shaken endlessly, which with a GS tank could take a while. I'd speak to a vehicle restorer for a chemical solution

Took the tank off today. I have no idea how I got the impression I was seeing paint strips floating in the tank. All I could see was small flakes of paint, some very shiny patches of steel and some worrying strips of bubbling paint.
I might just scare the bubbling paint off and see what happens next.
No rust anywhere which is good.
I will give the tank a good clean out as I am waiting for other parts to arrive from the UK this week

Well the floaters where a load of bollocks. I have no idea where I got the notion I had seen paint strips floating around in the tank as you cannot see into the tank
But as I have the tank off to replace the battery and throttle cables I thought best get to it and have a look in the tank. I bought and inspection camera and stuck it into the drained and defumed tank and saw big blisters of paint and a few patches of shiney steel.
Not liking the idea if swilling paint stripper around in the tank I thought up a cheaper and easier way to treat it.
Dont treat it, many bikes came with unpainted tanks so as long as I keep it with fuel in the tank it should be ok.
But the blistered paint had me concerned so I grabbed a paint scourer and stuck it on bent length of conduit and went to it rubbing the damaged paint back to good paint and metal.



The green is to do with the camera setting on my phone and this is after I had scoured.

A wee tip don't drop your phone into the tank when trying to take a photo.
