Rust-Oleum on old car?
Hi,
I have a 1980 Buick with rust problems, principally from two sources: It was in a rollover awhile back and got scraped up on the roof and sides, resulting in rust in those places. And the shoddy paint is flaking off on the sides, causing rust speckling. The rust is bubbling up in a few places but is mainly thin surface stuff. The car has high miles and will never win a beauty contest, but I would like to avoid getting rust holes, especially in the roof. My idea is to quickly sand off as much rust as possible and then slap on some rust-oleum paint. The idea is to stop or slow the rust- I don't care if it looks good. Do you think rust-oleum would do a good job in this situation? Big difference between spray-on and brush-on rust-oleum? Also, it says it has to be 50F to apply. If its slightly colder does it matter very much? (My main experience in rustoleum is on an old rusty kid's wagon I redid 17 years ago. The rust has yet to reappear). |

There is a product that is sold mainly by old car restoration shops /
magazines that turns black when it dries on rust. Basically turns to tar and seals it in good. I restored a 1969 Opel GT (notorious for rust) and used it in places where the rust could simply be sanded off. Worked wonders for years! Can be painted over too... So I'd suggest getting it (sponge or brush on liberally) and then coat it with the rustoleum or similar paint. ....Also, for a quick fix, you could rub some thick grease or motor oil into the rust - but don't ever plan on painting the car if you do that. Vasoline works well, but this is really not a great way to stop it. Just to slow it down. Body shops suggest coating bare metal ASAP with oil so they don't rust if you can't fiux them anytime soon... But they replace whole panels usually so the oil is not a problem when painting.

I'm working on a '36 truck restoration and there is plenty of rust
(fortunately they put a lot of metal in trucks then).. The method, currently used by many, is to treat the rusty surface with a rust convertor.. As Joe mentioned, it turns the metal black.. This stuff is a solution of Phosphoric Acid (with Tannic Acid) and reacts with iron oxide to create a barrior. It then necassary to put some paint or primer over it because it won't survive the sun or weather.. Check with any auto part store or auto paint store and get bottle of it. I have seen it called Rust Buster or Rust Convertor, etc. (Sea Story: When I was working in the shipyards I found that the frugal fishermen would use this stuff by the gallon on their ocean going fishing vessel.. During the fishing season this stuff was used to 'arrest' the bleeding rust where the paint system might have become damaged.. No surface prep, just splash or brush it on.. The Phosphoric Acid needs to rust to begin it's chemical reation. When they would come into the yard at the end of the season, they would have the metal prep'ed and painted.. A final note.. you better wear rubber gloves since this stuff will turn your finger purple and it don't wash off. Steve |

When you see rust on old cars there are usually tiny perferations from the inside and nothing seems to keep it from bubbling. The OP's rollover is probably an exception because it's fresh rust. Cleaning, priming, and painting should work OK. I've been experimenting with a product called Rust NOt from the Painter's Supply store. I put that right over a rusty panel where I knew rust was coming from the inside and painted it. It's been over a year and there is no sign of blistering so I'm going to do lots more with that product. Grease is OK under the car, but not on the top. |

I had a '72 Datsun that ran great but was rusting away. I finally got
annoyed and hit it with Rustoleum Rusty Metal Primer , then brushed on a nice beige with a good quality brush. I called it a 50 foot paint job. You could not see the brush strokes from 50 feet away, and it never lost the gloss finish. Really didn't look too bad. Took about a quart and half to do the whole car.
