  1. I've used a similar product (Por15) on 3 tanks over the last 10 years.

    The first tank failed about two weeks ago and I'm replacing the tank as once the sealant is installed it basically can never be removed, which means you can re-seal the tank.

    Of the other two, one was de-commissioned after two year sand may still be perfect.

    The last one is still motoring along but is only 3 year sold.

    Would I use it again? most likely no.  I'd rather have a new tank built professionally as it would be cheaper and easier in the end.

  2. I've just had a POR15 tank repair fail after 9 years.

    The problem is once it's been done it can't be resealed by the same method.

    I can replace my tank (it's an 80litre car tank) without much trouble or cost but I have 3 other treated tanks and now I'm starting to worry.

    I must get myself a T shirt!

  3. Once cleaned up both cam and crank could be spray welded or welded and re-machined.

    We have at least one company in Australia who does that to build up cams for a hotter grind.  not the best way to do it but it works and these old trucks won't be doing 100,000 miles per year.

  4. I've used an irrigation nozzle with a pressure tank to spray inside pipes where finish isn't important but coverage is.

    A 5 litre pump bottle with a length of hose (put it inside an thin metal tube)  and a nozzle and you will be surprised at the result.

    If you really fussy you could put the nozzle on wheels so it keeps in centred and rolls easily.

    The other option is sit the tube on end and drop the nozzle in from above.
