Recently I purchased a frame that had been sandblasted, but left outside in elements long enough to develop surface rust. I tried taking it off with a grinder using a wire brush wheel. It was effective, but time consuming, and I realized it wasn't going to work in the nooks and crannies. Before I continue, I want to enphasize that this little hint is not for those trying to build a "trailer truck." This will not give you a mirror finish suitable for parking over mirrors. However, if you're like me and plan on building a truck suitable as a daily driver, this is a great solution. Items needed: - 1-2 gallons of vinegar
- 1 garden sprayer
- 1 can of laquer thinner
1. Apply a generous amount of vinegar using the garden sprayer. Be sure to coat the entire surface. Pay close attention to the nooks and crannies. 2. Keep it wet with vinegar for 10-15 minutes. 3. Neutralize the vinegar by spraying it down with water. Again, make sure you're thorough. 4. Dry the surface. You can either let nature take its course and wait, or you can use a compressor and blow it dry. 5. Wipe it down with laquer thinner to remove all debris from the surface. 6. You're now ready to paint. Primer is not needed because the rust is a natural etch, as is the vinegar. I recommend Derusto. You can pick it up at Home Depot. It's a very durable paint and costs much less than POR. |

Great tip Dave thanks, do you have to wipe it with the lacker thinner or can you spray it and blow it off?, that would help in the nooks and crannies I would think!..

Heres a good one but you have to be very careful with it. Miractic Acid will eat rust off your suspension parts, granted you only leave it in there until the rust is gone. I have done this and it works. Miratic acid is used to clean bricks on buildings and you can get it at Lowes or w/e you get hardware at. Be very careful with it, it will burn you sorta like stripper will, not like what you would think acid will do. I put my coil springs, A arms and assorted things like that in it and it will eat the rust off and on thick stuff like this will not hurt the metal. I got silly and put an bent up peice of chrome trim in it and it was gone in like 5mins so dont try that unless you have bent chrome layin around. I lined a box with thick plastic, put my part in it and left it outside to "bake" overnight, and checked on it until I was satisfied and then dried it immediatly and primered it.

Early last year, I read about a method used to remove surface rust. Mix dried molasses, (cattle feed), and water; then let your part soak in it for a week, and the rust is gone. I tried it and it worked.

Yeah, I use pool acid and it works good, the only thing is you gotta coat it right away because the least moisture and it will flash rust instantly!.. |

I didn't remember the mixture ratio, but I found a link that will help: www.syrupmakers.com/rust/. I used the dried molasses and used a quart sized coffee can of molasses to 5 gallons of water. I bought a large plastic trash can (with lid) from Home Depot and used pieces of wire to lower the items into the solution and left the wire (clothes hangers), looped over the top rim of the trash container. I left the parts in for 6 days, then rinsed with water, dried them off, touched them up with a scotch-bright pad, and primered them immediately. |

what about the inside of the doors, hard to get to with any kind of sander, would you use any of these methods, obviously the cattle feed one would be hard to do with a door

I tried it and it worked. Harry You forgot the part about adding one or two cows to lick the stuff off; therefore, getting the rust off of it. Course, the more cows, the shorter the process.  |
