I'm getting ready to do a major varnish project on my Grand Banks 49
and was thinking that it might be nice to have the teak more or less
the same color (some is lighter, some darker, etc.). The wood will be
stripped and sanded before I start with the varnish.

Does anyone have any thoughts, experience, whatever with staining
teak? If so, what type and color of stain would you recommend?

Is there any downside other than some loss of wood grain visibility?

I'm planning to use epifanes gloss varnish which builds up to a dark
amber color with enough coats.
