I'm thinking the best way to remove the rust without sanding off good paint is to use a dremel tool with a wire brush or some other attachment. Then use a small paint brush to add some primer and then find a paint that closely matches.

Any thoughts?

Thanks.

I might do Metal Prep myself. You'd have to apply it carefully and sparingly, and also keep it out of the rain until after you get paint on it. All of those are because it will sort of bleach/etch paint if it washed onto it. As far as I know you can only get it in gallon jugs, which would be the other catch.

Otherwise I don't think you'll be able to remove all the rust without removing existing paint. And rust under paint means you only see the bubbles when it's too late...

You need to clean off the small rust patches .Dont go mad ,the more you remove , then it will be harder to cover them up after. I would paint it with zink plate, its a primer also .Or red lead . Finish with your paint .Then wet and dry paper .Then finish off Tcut and final polish with wax . First use a Adremel with small grind wheel in it, use the very tip to remove the rust so you have a neat hole through the paint to the metal .A little filler to bring to the same level as you old paint.

I agree with optimusprime with the suggestion of a small grinding wheel with a Dremel. I also like to use their cutoff wheels number 409 or 420 (heavy duty) for grinding. You need to get all of the rust off including the rust "roots" that may go deep, otherwise rust will return. A wire brush on a Dremel will not clean the spot sufficiently.

You are lucky to have a colour that shows up the spots so you can repair them before they get too bad.

optimusprime,

Should this be the order.
1 - grind out rust with dremel
2 - cover with zinc plate (I have a can of this in my basement
Rust-Oleum Professional 15 oz. Flat Gray Cold Galvanizing Compound-7585838 - The Home Depot
)
3 - use a little filler (I guess something like bondo?)

4 - paint with a closely matched color

5 - wet and dry paper

6 - wax

Thanks
