Well, after just over a week, I have finally fixed the leaky wild tank and re-vamped it slightly...
After hiding it outside during christmas, the weather had made the paint crack and peel...
It had also been missing one of the plastic corners from the day I bought it second hand. While I was at Bunnings, I found these metal corner thingies which were a perfect size, so I set about cutting 4 corners to size...
There, they will look better than the original brown plastic
I then set about removing the old corners and silicone and scraping off the old paint...
At this stage, I was thinking about totally pulling the tank apart, but the panels were still strongly bonded, so decided to leave it as is. This may come back to bite me later, I guess time will tell. I re-silliconed all panels and created a nice thick seal, then applied the new corner thingamajigs, which hid my first couple of mistakes with the caulking gun...
