Well it is on the outside. Just in case should I do the inside too? And also should I send this to a body shop instead? That POR15 has a torch red color? That is the color of my stang.

 

Colors can be matched easy that won't be a problem. Problem will be getting all that rust out and making sure its out. Sanding it down or sand blasting to get all the rust out is the only way to be sure. If even the littlest bit is left it will spread again.

 

Por15 can not be used as a topcoat, the uv rays will damage it. Under the chassis is fine whe it will never see sun.

 

There is absolutely no rust on the inside. Just a little 1 inch crack and a handful of bubbles around it. I will get to it ASAP. Bad thing is I'm 700 miles away from home and didn't have the time to do it before I left. Fml

 

Or under a topcoat. It's not designed to be color matched either, just comes in a handful of stock colors.

 

Does anyone know how much this will cost? And are there any videos out there to help me?
