My tank has a big double dent at the back where it looks like an aluminium ladder fell on it, and it already has another area at the front where my magnetic tank bag won't stick

I reckon it has enough filler already, so I am really wondering if anyone has a tank that is not dented or full of filler that I can use to paint up. Don't care what colour?
What you got?
I am Newport South Wales, obv driveable distance would be easier, but I have got friends in most parts of the country, so may be able to sort something to save posting it.
