Not necessarily. That small of a hole may be ok. Although a small patch of fiberglass would be a much better base to start with.

Sound good to people that have used bondo before? How many coats and how much should I use? I'm also thinking of shaving the back emblem since I have a stupid type r one, not the regular Acura emblem.
After that, I'm going to sand down the rest of the trunk and somehow paint it, either I'm going to do the job in my garage with lots of heaters(Its about 10-25 degrees outside.) or I'll find someone with a shop to do it for cheap. I have to get it done over break or before spring so I can put my car up for sale.
What are your guys thoughts on this? Any tips? I'm going to practice on a piece of cardboard and hit up some tutorial sites still.
For the places you are going to repair, it needs to be sanded down to the metal. As for the grit of sand paper to use, 250 would be ok to "knock down" the bondo, but be very careful with this rough a grit as it will leave scratches in your bondo and your paint will look like crap. I would step up to at least 600 grit after you have it down.
EDIT : If done correctly you should need no more than two "layers" of the bondo. I would use Krylon spray paints. The tip that they use on their Fusion spray cans are great for this kind of work. If you take your time to prepare the trunk correctly, it is possible to do a decent job with spray paint. Generally 2 coats of primer, 3 of base, and 1-2 of clear depending.
