i got a crack in my sharktooth grill that runs along the whole top, u think if i ran a bead of that ZIP-ZAP stuff across it and sand it smooth then paint think it will do a good job
If it is not a butt joint it should hold good. It will not hold a butt joint all though I have not found any thing that will. I hit a road cone going 70 in my Dart one night and broke the grill. It was bad. I put it all back together using that glue and it has been holding up very well.
