Have my fuel tank out at the moment and noticed minor surface rust on inside surfaces. Anyone used one of those POR15 type treatments for the inside of their fuel tank?
yes, POR15 is the go.
no correspondence entered into
too easy 
get rid of the rust with some Hydrochloric acid or any other acid removing product b4 deciding on the POR15.
Even if the tank has a few leaks at present it is still a better idea to remove the rust b4 trying to seal it.
Another way is to braze a tin plate over the area with holes in it

x2 great stuff has the wash and all the stuff needed, and it seals it up good ,used it on my 73 bays tank which came with a cup of rust when i bought it before treatment what it looks like after treatment |
Is it fairly straight forward to do this? My
only concern would be if there was some kind of reaction/paint didnt hold it would be a bugger to sort out...
pretty straight forward ,as long as you follow the instructions ,you should have no problems
These guys are the main importer for POR products

well my idea comes from specialist fuel tank reconditioners in the UK.
The hydro removes the internal rust and then brazing the patch on makes it liquid tight again. If you wish to stop further internal rust then use the
POR15 on top of this.
It you're going to split the tank halves then you'll have to drill the spot welds out and then use a blowtorch to melt the solder and slowly prize
the hlaves apart as the solder becomes liquid again 
The two halves are 'seam welded' - a continuous resistance weld, and not spot welded. It would be almost impossible to separate the flanges.
Do not let any welding torch [gas or electric] anywhere near a petrol tank, without taking the appropriate safety precautions.
Unless there are big holes, or serious rust in the tank, POR 15 should work.

Well, I have done the treatment so thought I would share my experience.
Kit was more expensive than I thought at $140 but it did include everything. A fair bit of cash to spend on a tank but these things arent that easy to
find a decent replacement anymore. Worth looking after if you have a good one.
The overall process takes a bit of time and labour but not really that difficult. Overall finish inside now looks good so hopefully time will tell and
this stuff lasts.

Bloody hell Aussie, you must have a really small camera.
reminds me of what the KBS process looks like which POR15 is the same just the paint is different formula.
I shoulda pointed you at these guys to save you some cash, including postage.
POR15 Tank Kit from Frost UK
Exchange rate is well in our favour at the moment and postage is generally cheaper than from the USA
Oh, I also found this made by RustBuster
