Undercarriage Rust?

[aforsberg]

Hey, I bought a fixer upper, and already sanded/painted the top and it looks great, But now I can see there is a lot of rust under the cart and I was wondering what I could do or what Products I could use to protect it....?

Thanks!

power wash first. then wire brush it or d a sand it as best as you can. you have to draw the line on how clean you get it'. just remember paint doesnt stick to dirt. then i would seal it with a epoxy primer. get it at any paint shop. i prefer a ppg product called dp40 epoxy primer 1 to 2 coats then just dust it with a flat back . good luck

Body shops are using some stuff called "POR-15". They say you cover the rust area with no prep and it stops the rust dead. Sand the por 15 and paint over it.
It's only available at auto body paint stores. We got some for a roof of a van. We'll see....

POR-15 is a high-tech, high performance rust-preventive coating designed for application directly on rusted or seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won't chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture.
POR-15 is sensitive to UV light (sun) and must be topcoated before prolonged exposure to sunlight. POR-15 is cured and strengthened by exposure to moisture and will dry faster under extreme humidity, but moderate to dry atmospheric conditions are most desirable when applying this product. That�s because extreme humidity may cause an immediate surface cure, trapping carbon dioxide gas below the surface. When this happens, bubbling may occur. Extreme humidity at the time of application may also interfere with proper adhesion of the POR-15 coating to bare metal because it is almost impossible to keep the metal dry under such conditions.
Use it to coat rusty frames, floor pans, farm equipment, marine equipment, or even a heavily corroded battery tray.
Typical cost of POR15 is around 25 dollar a pint .
good luck.
