Just wondering if anyone knows how to remove rust from the INSIDE of box iron?
I'm doing a frame off resto on my truck and need to know how to get rid of rust inside the box frame.
Can't get inside with the sandblaster.

I'm thinking some sort of acid dip or something?...

If anyone know how I'd love to hear about it!

Thanks!

sand blast it thats really the only way i know how

what is the consistency of POR15? possible you could by some and use a spray gun to spray in there? it wouldn't remove it but it would convert it on the inside... maybe i have the wrong idea about this stuff, i've never used it.

If the frame is bare you could stand on end and let the flakes fall out , with some tapping help. Then get a loooooooong wand up in there n apply used oil or something like that, or POR or Rust Bullet.

Start with a better frame.

Long wand sandblaster is the only thing that i can think of. and then use the same technique to paint it. Just make sure to cover all surfaces so you don't have the same problem in the future.

I think Slacker covered some of his frame work on his Trekker frame in his Trekker build-up thread.

I've done it a couple of ways

"wet blast" ... which is a hi pressure water based "spray" which includes sand ... works awesome , but expencive


I have also spent my own personl time doing it , about 6 hours , with a hi pressure hose banging and scraping




then both were frames treated with POR 15 inside and out .. using a "wand"

I cant afford to do a strip down to frame, but the wand set up will work, can you give more info on that setup.

It's something that you can rent from homedepot or lowes I believe.

fireman1559

or any equipement store like around here mullins should. but i would have to agree with the above post lowes or home depot should carry them to rent

Do you know if it will pass a thinned down oil of sorts.

Tbeck792

I wouldn't use a sand blaster for that. Any kind of paint sprayer should work though.

Teuf

I would think a blast of used motor oil inside would work, but i have always wondered if later you welded something, would it kind of burn in there a bit.

use POR15, its like 50 bucks but totally worth it..

runnerboyy

it would prob take a gallon.... its almost 150 bucks.

Someone forwarded me a link to these guys.
It's what I'm looking to get done but to far away.
Gonna do some more digging and see if I can get someone closer

dumping oil into your frame is NOT an enviromentally responcible thing to do .. it is like driving around an oil slick ..


although it will work for a while .. you will have to continue the process year after year

Well if i did the oil method i would let it sit for a bit, besides my oil pump drips too. Just a wee bit though.
