Surface rust What to do?

I was working on my buddies 39 Ford last night. Good solid car, very little cancer. All the rot has been cut out and new metal welded in. Along the lower, outer rockers there is surface rust. Not bad enough to cut it out but too bad to paint over. I figure the best thing to do would be to sandblast the metal clean. Problem is its on the lower outer, that means I'm laying on my back outside running the blaster. Not gonna happen! I was thinking that I could DA the surface, treat the rust with something, etch-prime and finish. Question is how to treat it. Are there any such products that work? Keith

 

Use some Rust Mort good stuff

 

OK Rip Van Winkle its time to waake from your 20 year nap and take a gander at how thw world has changed.

Rust Mort, Por 15, Rust Bullet, hell Rutoleom even sells a product. The list is even way longer than that. Some of the products use an acid to convert the rust and others encapsulate it, either will work.

here's a trick that i learned from Mr Roth when I was a young man. Take a wire brush to it and clean it as well as possible, that is going to involve laying down if it is a rocker cover. Now take the resin part of fibergl*** and paint over it with that. Now finish prep and paint. The resin encapsulates it so that it doesn't continue to rust.

 

You know pork, had I not been reading your posts for as long as I have I would have taken that as an insult!!! I knew of those products, I guess my question SHOULD have been do they work? I was considering POR-15 for the inner panel, I am a bit worried about painting over that stuff Any body guys want to chime in?? I am also aware about using the tie coat stuff to get the paint to stick to the cured POR 15. I remember back when I was in High School and was sweeping floors in a body shop they used rust-Mort but I was not sure if something better had come to market.

While at work today I had convinced myself to do the job right if I am gonna do it. Either DA and sand blast, or DA and wire cup the area, Etch prime, Epoxy prime. He wants body schutz on the lowers, I'm thinking UPOL's Raptor product (I love that stuff) Thoughts? Keith

 

Damn , Beanno ......easy on the guy. I just woke up & was going to ask the same question. (RUST ****S)
"AND THE BOWTIE ROLLS ON"
thanxz for the post .

 

let's see - metal rusts - whatever you do, the metal will rust again - it's a matter of time to rust - some delay it better than others

 

blast it, you know its good then. thinking you should be able to jack the car enough to avoid laying on your back?
Ive never had luck with wire brushing, bear down on the thing and still have rust return after some time.

 

if it is just a light coat of surface rust, then you should be able use a scotch brite (red) and some phosphoric acid (full strength. the neutralized with a water soaked rag)..if the rust is more than light surface rust you would be best to blast it the da with 80 grit, then the scotch brite/phos. acid step...make sure you get primer on the metal asap or you will get to repeat the process...and use a decent/good primer

 

Ospho; Jasco Prep and Prime, or others. Phosphoric acid treatment.

 

Thanks guys, I've got it out in the driveway jacked way up on the one side and waiting for the weather to co-operate with me. Then the DA and 80, then blasting it with ****-magic (crushed auto gl*** about 36gt) then the ospho treatment followed by etch primer and epoxy primer. Keith
