preparing inside doors and other panels to prevent further rust

[ArtT]

I have a 55 Chevy Belair and I am in the process of replacing the lower door frame and lower door skin to fix rusted sections. I want to treat the inside of the doors and rear quarters to prevent further spread of rust. My initial thinking was to clean up what I can reach, then use a rust encapsulation paint for the old metal and epoxy primer for the new metal. After reading posts in this forum I see a rust encapsulation product is not recommended. What is the proper way to treat the inside of the door?

Thanks,

I poured expoy into mine, several times, and rolled the doors around so that the seams wrere hopefully all filled and or covered with an air tight epoxy seal.

Easy to spray inside when the bottom is off. Sanded best I could and epoxy everywhere I could shoot.
I'll be gone by the time it may rust, so who cares?

I had quite a bit of access in this case, but with a narrow fan, easy to spray.

how much effort did you take to clean up the rust? I used to spray lacquer 30 years ago and it seemed so simple in comparison to today's paint technologies. All I keep reading is the potential problems with epoxy adhesion and other problems if the prep isn't just about perfect. So in my case with the surface rust all over the place - will I have a problem? The attached picture was taken after I spent time wire brushing inside the door - although it doesn't look it. I also guess I should remove all the inside hardware before painting it. Although I have the bottom off this door - I won't on the second of my 2 doors not to mention the rear quarters and lots of other areas. I also have seen an undercoating spray gun which comes with extension lines to get into tight spots. I am thinking that would really help with all the areas I need to get to.

Thanks for your response.

That looks great. I would love to see the before picture to get a sense of what it looked like before painting. I am assuming you used SPI epoxy. I too don't have to worry about forever at my age . I have been told if my 55 lasted 67 years - I won't need to worry about the next 67.

I use epoxy where appropriate followed by cavity wax.

So where you say it is appropriate for the epoxy - do you mean the inside of the door but not on the window and door lock mechanisms? I understand the cavity wax would be extra protection. By the way I like your profile picture - nice car.

A little bit of surface rust, but doesn't worry me. Considering there was no paint on em for 80 years before I applied this.

.
By appropriate I mean where it will properly adhere. I treat bare shells without tracks, locks etc.

Is that a California car? I have a lot more rust on mine which was located in New York. Thanks. Art

That has been my plan for some time... After all paint is complete!

One door was media blasted on the inside where the sound deader wasn't, the other I did the best I could with mechanical means before I patched it. I kind of wish I had taken the skin off then cleaned it. but I'm hoping the pour job will hold it for 20-30 years.

I would be really happy with 20 to 30 years - I doubt I will make it that far but if I do I am sure I would be too senile to notice . Thanks.
