Default C4 Floor Repair

I need to fill a hole in my 1986 passenger side floor. Looks like a previous owner put a jack or lift too close to the floor. It has a hole in the corner that is about the size of a quarter.

There is also a crack on the passenger side footwell...I believe that is from when I went over a speed bump because I remember the car making a noise.

What is the best product to use for these repairs? Bondo?

Thanks!

How big is the hole? Only after properly preparing the substrate to accept any repairs, if the hole is big, make a patch out of fibre glass first then install it in the hole or if it's small, put some masking tape on the back side of the hole and then patch it with some 'glass, the same goes for the crack, but what ever you do, don't use bondo.

THanks!

Like I said in my original post, the hole is about the size of a quarter. It is right on the front outside corner of the floor...right where someone probably put a jack or a lift.

It is a nice day so I may try it today.

Ok, now I saw it. If its the size of a quarter and it's not in a structural support area or prone to any abuse and all your wanting to do is seal up the hole, prepare the adjoining area(don't forget to 'v' it out some) so the resin will adhere to it, put some masking tape on the bottom side and mix up some glass mat(not cloth!)and resin together and lay in that area and smooth out. Let it harden up(a day depending on temps.)on the bottom side, if looks are important finish up with some 'glaze', prime and paint if it's painted or just undercoat it and on the top side, lay your carpet back down, no one will be the wiser and it was done cheap.
