What happens in the Garage STAYS in the garage (unless its a bike, then it comes out now and then)
Looking much more like a bike now mate. As for the dent in the tank, im not sure if this will work due to how thick the metal is but i have used a toilet plunger on a couple of car door dents to pull out, again im not sure if it will work due to the curves of the tank and the fact that the car door skin is a heck of a lot thinner.
Worth a try if you got one at home and its clean
