The underside got painted too for protection. This repair will make the seam much tougher in the future when I put the floor jack under there for lifting. It will make it too wide for the jack that comes with the car but that is not an issue for me. I will simply slide the jack a little further over in an emergency. I did this mod because I could see further damage occuring everytime I lifted the car with the floor jack. Since my car is lowrered this is about the only safe spot I can get the jack under. I also noticed it will help deflect speed bump hits when you go a little too fast over the parking lot bumps.
