Brushing on Oxalic acid?
So I've got a couple of chains soaking in oxalic, and it's amazing! Anyway, I'm thinking of stripping and repainting the Raleigh myself (probably a solid color, with a contrasting head tube) and later going back to the original color scheme.
So, my question is - do I need to completely cover the frame in a pool of acid, or can I just sand the edges of the paint smooth and brush on the acid?

I would not use oxalic acid as a paint stripper. There are specific products for that. One commonly used is aircraft stripper. Works well.

I think for oxalic acid to work well it needs to be immersed in it for a period of time. For spot treating rust, something like Naval Jelly would work better.

No, I'll be using something else as a stripper, I'm looking for rust help at this point - I don't want to sandblast something that is barely mm's thick.

I have successfully made a paste of OA and a little water and brushed it on. I think it only works when wet, but it does not take a lot of water. You could also use a large trash bag instead of a pool, and then it would not take so much liquid. Might have to slosh it around frequently though.
