And that is what was under the paint and 4 kg's of bog.....home handyman shit.... argh, the dangers of the 4 inch angle grinder....even the filler neck was damaged by whatever they used to try and pry the dents out, they had cut a hole underneath aswell to put a punch up the inside for more "handywork"....guess what...doesnt work. The pictures dont show how bad the tank really was.
