rear rocker panel rust

im sure this has been asked 1000+ times but i will do it again..

I have... no, I am MISSING,,, about 5-6 inches of my rear rocker panels, both sides...

is there a cover for this problem.. like a plastic cover of sorts or do i have to replace the panels period?

There are plastic trim covers available. I am told that they are no longer manufactured. You may find them on ebay. I have a similar problem. I am going to cut out the rusted section and replace it with a rocker panel from a parts truck. If you do cover the arrected area, you still need to stop the rust or it will continue to spread.

you would be wise to repalce them with fresh metal
