I tried that along with charcoal at the same time, for 2 wks on my covered porch...didn't work for my rattan chest. I am so glad I painted w/ the clear poly finish. For your piece, I would sand lightly the varnish so the new finish would adhere. But first I would test a spot ( on the inside) to see if the 2 finishes are compatible. You know sometimes the new finish doesn't want to dry. I was working over red paint.
