Rusty Metal Primer, Etching Primer or Rust Reformer??? See pics.

Looking for opinions: Time to address the rust issue on my 2010 Silverado Crew Cab, rust has formed behind the bottom of the doors' lower weather strip which has started to now push the paint off the bottom of the doors to the bottom edge seen from the outside of the truck. After taking the majority of the rust off should I use a rusty metal primer, etching primer, or a rust converter??? Then topping off with either paint or rubber coating.

 

 

 

 

P.S.

 

Even though the truck has been regularly washed and waxed, I am not overly impressed with how the paint has held up for a truck that is garaged. A month back on day I noticed a bunch of bubbles under the paint on the driver's rear door. I took a pick and found rust-through holes that formed from the inside out.

Yup, that looks pretty standard for a GM of that age. I had to wire wheel the rust from the inside of my door seams, treat with rust mort, prime with an etching primer, then I resprayed the bottoms of the doors.

 

My rear fenders have been getting rust zits and holes like that, so it's been a constant battle to keep fighting them.

After wire brushing I have decided on using Por 15, etching primer, then rattle can bedliner...will post pictures when done....

Fix,trade new truck

Why fix it and then trade it in?

 

Either trade it in "as is" or fix it and keep it.

 

 

It's a 7+yr old truck that lives in the rust belt. That's expected.

Because rust is a cancer. You can never get rid of it. It takes root further it will be worth nothing. You can't fix it for long term. You jus stop the rust for awhile.

Wire brush from drill >>> Sanding drum on Dremmel>>>2 Coats of Por15 >>>3 Coats Duplicolor Etching Primer>>>4 Coats Duplicolor Bed Armor Spray...Plus some bondo where I lost the seam.

I'm a big fan of enrust. Two coats, two coats primer, two coats paint. Fixes rust on steel hulled boats floating in salt water every single day. Should be fine for a truck that sees salted roads.

Use two part primer and paint if you can. Will never see rust again from that spot.
