I wanted to add a word of advice here. I'm sure the bondo will hold up just fine, however a more robust option would be fiberglass strand plastic filler. I say this because it is hydrophobic, unlike bondo which will expand and contract as humidity levels change. this could cause cracking. Also the fiberglass strands in the fiberglass strand plastic filler help to hold things together and is much stronger. just a tip from a body guy for those who may be concerned
