Varnishing with Damvar varnish

Quick question about using Damvar. Has anyone put two layers of Damvar on their oil painting if the first coat looks like it “soaked in”? I painted on Multimedia art board and it was quite absorbent. And for the Damvar varnish generally, one coat should be fine usually?

I did go ahead and put another layer of Damvar, but it didn’t seem to change anything … so I am ok with that.
