Rust in tight places

I'm removing surface rust on a 4130 fuselage prior to priming.

Assume I'm in a place where I can't use my sandblaster.
I need to get into the tight places of a cluster to remove surface
rust.
I can get pretty deep in the cluster with emery cloth, but there is
the last 1/8".

There are rust converter chemicals on the market. Is it OK for me to
use
a rust converter prior to priming or am I fooling myself? - Mike

get a finer grade of blasting media.. I can't see how you could get
any better results any other way.

I think he meant that he was in a location i.e. hanger where
sandblasting was forbidden.

That now does make sense but if the rust is slight there are small,
portable sandblasters that would work using the smallest compressors..

use a brass wire brush and Phosphoric acid - MetalPrep or Water
Softener Resin Cleaner - same stuff at about 1/4 the price.

Clare - I put a coating on part of my fuselage to get rid of rust
remaining after wirebrushing. How long should it take for this stuff
to dry? - MIke

Do you have a specific brand in mind?

I have never used one on 4130, and never heard of one used on aircraft, but
I have had good luck on automotive applications.
