I think the fact that paint markers (including Gundam Markers) are alcohol-based needs to be emphasized, because it means that using them on top of anything else will just ruin everything. You might be able to get away with it if you use the Gundam Marker airbrush adapter and stick with light coats, but as a general rule of thumb paint markers should be your base if you plan on doing multiple layers.
Yeah, alcohol is a solvent, and can certainly mess with other paints. That said, I do use them for detailing on my painted builds, but I spray a gloss coat first to protect the paint layers.
