surface prep w/ water soluable oil?

[john.red]

Hi Everyone!

Quick question. I know with regular oils you have to totally seal your surface to prevent corrosion, esp. if painting on board or paper. Does this also apply to water soluable oils? I imagine I'd still gesso just to make the paint go on easier, but would it still be neccesary to do several coats to seal the surface?

thanks!
