Soap Box Derby - Body filler question

This isn't a Jeep question, but it does deal with body filler so I'm hoping I'm in the right section...

My son and I are building a soap box derby car and the body is going to be masonite hardboard (brown colored 1/4", slick on one side, rougher on the other). We're looking for that smooth look so I want to put body filler over the screw holes so that it ends up being smooth and then we'll paint it.

My questions are: with body filler hold to the slick side of the masonite hardboard? Will I need to scuff it? Will the body filler eventually crack on me with all the bumps (small wheels) and the fact that the body will probably not be 100% solid (the frame will be all wood/2x4's, so I'm guessing it'll have some play, I'm hoping for none). Any tips on body filler for this application would be great.

Thanks,
Pete.

U might have already got ur mat. But if u have not i would go with 1/2 or 3/4 BC plywood . Then get a kreg kit and use pocket screws and wood glue. It's easy to use and makes a super strong joint and screw holes will be on the inside.

Bondo does work on wood with the smooth surface of masonite you'd probably need to scuff it up for it to hold best. Personally I would go with plywood like BDP72 suggested. If you take your time with sanding you can get it incredibly smooth.
