I purchased a Auto Couture Kit used. On one end a side skirt, it is cracked, not by much. The kit is already painted, so I don't want to bring it to the shop and get it fix then repainted. I was wondering if there is a way to repair it from behind, so that it won't crack even more.

 

Bo to a shop and tell them to fix it and just blend the area, not the whole side skirt.
