How low are these spots ? If it's a significant spot, use Marglass and resand, otherwise body filler is your best friend.

Just LOAD on the bondo and then use a latex glove and your eyes and hands to get the right "curve" you want, then clean it up by hand sanding it lightly, making sure to keep the curve you want. Make sure not to load on the bondo then go in there wiht an electric sander, too much can sometimes be to much. hope that helps

What are you sanding with? I know from experience that sanding by hand or with a block sander on concave surfaces just doesn't work. To get the enclosure to flow nicely, I highly recommend using a foam sanding block. It forms to the shape easier. Maybe you already are, sometimes a certain area just seems to take forever.

The best material to use for "filling" is Rage Gold from Evercoat. This is the stuff all the pros use - The Alpine Mini Cooper has 50gal in it. (before sanding) Steve Brown from Alpine swears by it. Its easier to sand than Bondo - has a nicer final finish - Then use the heavy primer for pre-paint.
