Back Blade cleaning

[TheMan419]

So I got "donated" an old 5 foot back blade. The adjustment for changing the angle of the blade works. However the blade, and frame and all of it is just a rusty ugly hot mess. So I got the idea in my head to clean it up and paint it yellow to match my tiller and bush hog.... and frankly a good coat of paint will keep it in better shape for years to come.

Is this the right attachment for my grinder to remove the paint and rust?

I know total newbie question, but I have never done this before. I have a corded Porter Cable angle grinder. I have used a cut off wheel as the only real attachment for it.

Then paint like this Majic Tractor, Truck & Implement Spray Enamel, Case Power Yellow at Tractor Supply Co.

Although that seems to have a bit too much orange in it and I want a bit brighter yellow.

That disk will work, but they seem to clog up quickly. I like the real heavy duty wire wheels for angle grinders or drills.
Read up on adding hardener to the paint.

I second the wire wheel for cleaning things up. I find that grit paper works more quickly at first, but then clogs up. A wheel is consistent. Wear safety EVERYTHING, as wire wheel, besides tossing rust and paint, will shuck some of the wires as hot pointy projectiles. I use one to clean up before welding.

So more like 4-1/2 in. Carbon Steel Knotted Wire Wheel

You can use one of the extra coarse wheels like you linked, but they do wear out fairly quickly. I use a wire wheel like the one posted above, most of the time. I only remove the heavy loose rust. I leave the tight rust and create a tough base with Rust Reformer. https://www.menards.com/main/paint/...83-c-8012.htm?tid=8817839443478398702&ipos=31 That stops the rust and makes a nice primer for top coats. I like brushing on 2 light to medium coats of Rustoleum enamel. I've done this to several attachments including a heavily pitted and rusted back blade.

I agree with this. Using rust reformer or at least a primer for rusty metal then brush coat the paint on seems to last a lot longer than spraying in on. I used the primer but sprayed on 4 coats of industrial Cat yellow on my snow blower and front plow and a lot of it has come off. This summer I'll be re-doing them again but brushing the paint on.

Take it to a local sandblast shop and do it there. We have one nearby that has a booth big enough to do a large utility trailer and they charge a few bucks an hour. YOU have to do the work but they provide sifted media and a hood for you.

Sandblasting was my first thought, if such a facility was locally available. That would give you the best results. I never heard of a do-it-yourself shop until now.

Don't buy that Majic brand sold at TSC.
Go to your local CAT dealer, and get one of the two yellow colors they sell.
(I believe that theirs is Sherwin Williams, but with a CAT label).
The CAT paint is just about the same price as that TSC Majic junk.

Sand blast lot quicker compare to man hours etc. by hand...take apart as much as you can.
