Easiest cheapest way to fix dent

Chryslerkid said
I am trying to fix a small dent... well multiple small dents on the cheap. Example below. My plan is to use the original faded paint on the barracuda as the primer coat sand with some fine grit and do some minor bondo work on door dings ect. Then I plan on spray painting with rattle cans with a 2X rustoleum paint primer and paint included. I am choosing a brighter color close to a B3 blue. My question is what are some simple steps to make sure bondo sticks to these small dents/dings?

180 grit is as fine as I would go but if you can get behind the panel and try to push the dent out as much as you can that would be the best.
If you are not using a etch primer on bare metal than I would sand the paint and try not to hit bare metal then use bondo, glazing putty would be best as it sticks better to a finer sand paper.
Are you planing on painting the entire car with rattle cans?
