pick a smoother watercolor paper, and/or consider a larger rapidograph or bold fountain pen w/ waterproof ink

A larger rapidograph will require me to make larger letters
I have several fountan pens but I didn't tought they could work well on watercolor paper.

>rapidograph on watercolor paper
That sounds like it would destroy the needle in no time.

If you already have them, why not try it out?

You could also o the ink separately and shoop it together if you're married to incompatible tools.

Disposable pigment liners (e.g. Sakura Microns, Staedtler Pigment Liners, Faber-Castell PITT pens, etc.) will work just fine on watercolor paper. They were originally created to replace Rapidographs, after all. The rougher surface will wear the nibs down faster than ordinary paper, so try to keep your touch light.

You could probably find illustration boards that are smooth enough to work with a Rapidograph and still not buckle from the watercolors. I've never tried this though, and illustration board is expensive.

I've tought about that, I just feel it'll add more to the process but it seems the best option.

They can work. The smoother the paper the better, as well as experiment with nibs.

One problem is though that though there are waterproof inks (a lot of fountain pen inks aren't so choose wisely) is that a lot of pens, especially flex pens put out a lot of ink so that even though the ink that binds to the paper won't budge the extra ink laying on top of the other ink will begin to run and mix with your watercolors and make it ugly.
