Question New Snowblower ALREADY Rusting. Tips for prevention?

I used my new Toro snow blower about 5 times this year and already i'm seeing significant rust within the busy end. I was expecting rust to appear 12 months from now not within 1 month. Sheesh. I figure the problem was rocks slamming into the paint exposing the iron -- mixed with the air and water the corrosion went to town. Before the winter started i applied a generous amount of Fluid Film on the inside.

Anyway was wondering if you guys have confirmed strategies for stopping the rust THEN applying a durable coating to help greatly reduce future issues. I was thinking

1. Wire brush any loose rust
2. Apply a generous amount of some Rust Converter -- i live in Canada so we only have Rust Check -- this never works for me
3. Spray a generous layer of some paint enamel OR 3M Paint Defender Film or a Truck Bed Liner.

Your thoughts?

This is unfortunate.

Odds are the metal wasn't cleaned properly before the housing went into powder coat. And once powder coat fails, it is very difficult to halt the corrosion without stripping and starting over. The coating traps the moisture underneath and odds are it will be coming off in big patches. You certainly can try treatments and paint but I haven't seen many examples of success doing so.

There's just one thing I'll guarantee , the best things in life, they sure AIN'T FREE !!

Can you disassemble it and take it to a good commercial powder coater to do it right. Sand Blast it prep it and powder coat it. This doesn't sound right as stated above.

My MTD although quite a number of years older, is doing the same thing. I had paint flaking off in areas in large pieces and I have found that Rustoleum spray primer with the rust inhibitor seems to do the trick, provided you don't care how the machine looks. Any area I noticed that had rust, I sprayed with this and I haven't had an issue since. Been using it for years like this now. The machine's overall value doesn't justify me tearing it down and getting it powder coated and I don't care how it looks, function over form for me. Not an ideal look but the Rustoleum definitely did the trick in stopping the rust from getting worse.

If it's within warranty maybe you can get some relief there?

POWDER COATING STINKS. Once it chips water gets under and because it's a hard film it comes off in sheets and can NOT be touched up. Use Rustoleum red oxide primer and oil based enamel paint. As far as rust removal if you get a quart of phosphoric acid from a paint store or home center (it may be sold as concrete or metal prep) it will convert any rust you can't sand off to a paintable black surface and etch the clean metal.

I'd spray the inside bucket area with a light oil a couple of times a season and once before you put it away for the summer. You'll probably be long gone before it rusts through.

I'm not looking up the specs...BUT are manuf these days PC the buckets or paint. I would think paint, since it's cheaper off the line....

I've used powder coating on a lot of things without a problem, however I have a local professional shop that is very conscious or prep. I have had good luck with their stuff on car frames and such. Perhaps a snow blower isn't one of it's best applications.

That being said, acid does work great, good idea. I forgot about that. But one thing with acid, you have to prime it almost immediately or else rust develops. I've used Muratic acid, not sure if it matters.

Great question, I looked it up.

Under "frame warrantee" it addresses rust.
