rear hatch rust around the hinges
 

i guess the title say it all LOL is a 1997 4 door with the hatch that lifts up, the kids call my truck buckets because well that's how i catch the water,, roflmao.. the rust is getting really bad in the area though and i wonder if anyone has repaired this area and how to do it or if anyone has tried a short bed conversion, which i think would be kool,,,,
sorry if this is duplicate but i could not find similar topic
