Undercoat????

On my 1985, T1350 Saturn you can see the frame rails when you crouch on your knees. Mine has the typical pitted rust, but only superficial. Mainly for cosmetics, I wanted to repaint but even a spray-on Tremclad treatment wouldn't do too much justice. I was wondering about a spray-on asphalt/rocker guard (undercoat application).
Just curious what others have used for their older trailers? I have considered a brush-on enamel, rattle cans and rocker-guard spray. But when doing the frame rails I'll also redo the front "A" frame and rear bumper too. I even considered taking it to a body shop for a paint job of the frame, nah, too expensive and kinda silly when I can do it myself.

From past experiences I found spray paint has too much lacquer and not enough substance in paint. Brush-on can leave visible brush strokes. Rocker -guard might peel after a while. I did repaint the rear bumper and front "A" frame with Tremclad 2 years ago and it looks like a shoddy job (BTW I am nothing close to a body and paint person.
Thoughts???

I have done the camper frame before on our last camper and planing on doing T310SR, maybe yet this year. This is the materials I will use on the T310

After sanding, wire brushing and grinding... I start with Eastwood rust converter to stop the rusting action. This product Eastwood Rust Converter | Rust Converters | Auto Rust Converter

Then there is rust encapsulation. Eastwood Black Rust Encapsulator - Paint Over Rust

And then, Rustoleum Pro oil based enamel.

Professional High Performance Protective Enamel Product Page

Yes, it is a long process. But after all that prep work, you do not want rust bleeding back through again.

Here are pic's of when I did our prior T2499. This was only the Rustoleum paint. The rust did not advance as much then











Ideally get the camper up off the ground on stands. These low riding campers are a "project" getting under then. And yours is lower then our T2499 was.

Hope this helps

John

Thanks for your help John. I wasn't sure which way to turn. I power washed the existing surface and had some older cans of that rocker guard spray stuff so I decided to attempt to start. It actually looks not too bad. I did notice the original paint underneath was that beige type color. So I might just paint over the rocker guard later if I feel it's necessary.
Right now it's protected and from a short distance it LOOKS renewed. I'll do a wait-n-see how the frame feels and looks before I decide what to do about the rear bumper, with respect to cosmetics.
Thanks again
