Hey man, I dont know what color or trim package you have, but I would think you would be better off looking around for a new front fascia either on ebay or from a salvage. I bet you it will be around $1000 (or more

) to properly fill those holes and re-paint your front fascia. And you could always run the risk of the filler shrinking and showing through the paint etc.
If it was me I would mess around at that price point. Ive seen front fascias on ebay going for pretty cheep.
Here is a silver SS fascia for $350 + $185 to ship from SLP. I would also call around to all of the camaro tuners besides SLP. A lot of these guys are taking brand new parts of brand new cars and they have a lot of stuff laying around.
I know your in Florida, but there is a salvage yard here in Waterford Mi that specializes in late model GM

Good luck to ya
