Hi,
I'd stay away from the Bondo unless you have rusted thru places. To use Bondo, it is recommended that you grind and roughen up the area to be filled. You don't want to grind your chassis up like that. Applying Bondo to a slick or smooth surface may result in the stuff peeling or flaking/not ahering to the metal.
As an alternative, when you are ready to start painting, use a coat of primer (after prepping properly), Use it over the small pits.
Once you have the primer on, you use "sopt putty", comes in a tube from auto body suppliers.
The primer gives the spot putty something to grip to. If you apply putty to bare metal it will not hold.
After it's dry, block sand the spot putty level with the surounding areas.
You can add another very light mist of primer over the levelled out pits now.
Go ahead and do the painting. I agree that the bright aluminum or silver paint is gaudy and should be avoided at all costs You don't want something to blind you whenyou look at the back of the set.
The flat silver or even a silver grey will look good.
Many use Bondo for cabinet repair and such but Bondo was not made for a structural material. It either must have a bast to be applied to, or needs to be backed up with something more solid. A missing piece of cabinet filled with Bondo , and not backed up will eventually fail,or get hairlines where the repair was made. In fact for auto use, Bondo is not recommended for deep repairs like a large dent,. The less you need, the better. A thin coat is preferred after the netal is brought out as close as possib;e to original.
For structural repairs fiberglass colth, and resins are preferred. It is easy to flow 'glass resin on the inside, beyond the repair area for added strength.
Sorry for straying on the subject, it's late.
Take care,
Gary.
