Rust Dissolver

Beanhead said:

I am looking for everyone's input. I have used an angle grinder with a flapper wheel and wire wheel before. I had learned the hard way to definitely wear a good respirator and eye protection. I'm a young (born in 1965) lazy guy just trying to find an easier way to cut through the rust with the least mess possible. I'm not looking to do a full restoration, just want it to through the snow a little better without plugging up. I do add the rubber paddles and keep them just off the surface of the tunnel. I am going to try a couple more applications and see how much cleaner I can get it before trying to smooth the surface better before painting.

I like your thinking. Have done this as well with just flapper disks down to bare metal and then using rustoleum 2X paint and primer . only been doing this for 5-6 years and have not seen any reoccurance of rust. however my time test is really not definitive.

Have used POR 15 on the augers and impeller with excellent results. even after 4-5 years these parts still look brand new.
Have had a couple dozen sets of auger/housings/chutes and fuel tanks blasted and then powdercoated for the last 5 years or so and they still look like new. Actually inexpensive considering the long life we are going to get out of them.

First picture is a housing I flap disk sanded down to bare metal and then used several coats of Rustoleum 2X paint and primer.
Then a couple examples of shop blasted and powder coating. Average cost around here is about $165 for the housing/chute/fuel tank. Your costs may vary. There are a lot of these shops in the Reno area.
