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.

Ben

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
