Sanding Rust?

[Hick-From-Hell]

I am looking to re-furbish the old pull behind snowblower I have. I want to paint it. It is rust colored right know and I was wondering what you guys recomend to prep it for paint? Should I wire wheel it or sand it? The rust is only slight surface rust.

Greetings. For me, my prep will depend upon the surface itself. If there is any paint that is solid and not bubbled or chipping/flaking off, I just scuff/sand those areas well. For bare metal areas, I sand those well to remove the rust completely.

After scuffed/sanded, I then use a wax/degreaser to clean the surfaces and ensure a good primer or paint bond.

Bottom line here....the better you prep the surface, the better the adhesion of the new paint and hence longevity.

Would carb cleaner work as a de-greaser?

First, wire brush using a grinder with cup brush. Wear mask. Second, sand areas a little bit where there may be existing rust. Third, brush phosphoric acid on the entire unit. Fourth, take a rag with lacquer thinner and clean the unit. Finally, spray paint it in primer then your topcoat.

Carb cleaner leaves a residue, brake clean does not.

i usually will just hit it with a wire wheel real good than clean it with some brake clean and than hit it with some rustoleum primer and paint. let the primer dry on there real good


thats what i do

i had a horse trailer sand blasted and primed years ago and i ask the guy if that was a good primer and he gave me a screw driver and told me to try to scratch it off the five gallon bucket it came in. i couldn't. with an application like this i would contact a commercial sandblaster and follow his advice on a good primer. the other stuff you put on first neutralizes the rust and the primer protects that and the paint protects the primer. rustoleum paint fads ease after a while but it does stay on good. i've found the green paint for lawn furniture reallt holds up good and doesn't fade.
