Depending on which Clear, the full cure may not happen for seven days. It sounds like you haven't hit full cure yet as it will stay sticky until then but yes, you can pour another coat over it if you want to - it won't hurt a thing to do so.
Yes, simply measure accurately, mix thoroughly, and reapply and it should cover and crosslink to any "unmixed material" you might have had from the first layer and cure nice and hard for you. Only thing might be IF there is any substantial areas that look white, hazy, or are visibly noticeable on the first layer, they may still show through but most likely will disappear or be very hard to notice unless you are looking for it.
Hello Mike, I am hoping you might help me with this issue? I did a pour of deep pour last night, this morning it was still liquid, I did a second pour today and noticed the resin was very liquidy, I mixed the right amounts, by volume, mixed for 5 minutes and 6 hours later, it is still liquid. Any ideas? Thanks, Joel.
