Why try to get rid of the dent? A VERY old trick (that we used to use on car bodywork) is to get rid of the paint , in & around the dent, (scraper, glasspaper etc) then fill in the dent with a 2 part filler such as "plastic padding" or even fibreglass. When it's set solid, shape it with a sander, then paint it. Might take you longer, but it's sure cheaper. We learned all these sort of things in the days when money was tight, and before the era of "built in obsolescence" :2tup:

There are all kinds of tools a good body shop uses to PUSH out these kinds of dents. There is another method that is used - heat up the area with a hair dryer, then spray it with a cold spray can (like the compressed air to clean electrical components), or apply a piece of ice, to rapidly cool it, and sometimes the dent will just pop back out as the metal contracts.
Search the net for dent removal or go on You tube, you'll find these, and it doesn't mess up the paint at all.
