Question Epoxy pour over sanded or unsanded sealer?

Hello All. Noobie357 here, and as you may have guessed... I'm new. I have a quick question about epoxy.

My wife has a new island top that she stained with oil-based stain. I did a bit of research since she wanted that bar-top look in the end. I found a thread in this forum from 2014 stating that I needed to seal the oil-based stain (Zinsser SealCoat recommended), before applying the epoxy. That has been done, but I have not been able to find confirmation as to whether or not that seal coat needs to be sanded before the epoxy is poured.

I have poured epoxy before, but not over a sealer, like this SealCoat. I'm just trying to ensure I prep properly, because I really don't want to have to sand off an epoxy pour.

There should be a Tech Support tel. number either somewhere on the label or on the web for the epoxy you will be using. They are the best to tell you about compatibility with their product. If that doesn't get you anywhere, call the SealCoat manufacturer.
There comes a time to ask woodworkers and a time to ask the manufacturers. In the long run, the manufacturer is the one that is warranting and liable for their product not woodworkingtalk.com.

Usually, sealer will raise the grain a bit so sanding is needed if only to level the surface. I mostly hear sealer referred to as "sanding sealer" so the idea of not sanding it never occurs to me.
