I have 2 gallons of Renner 648 that are going to go to waste unless I can use them with some other paints that need to use on a project.

I am going to be using BM Advance and SW Emerald Urethane soon, and was wondering if the Renner 648 water-based urethane would be an appropriate primer to use for either of these.

Any thoughts?

I haven't tried that combo but I bet it would work fine. The Renner dries very hard so I don't think it would be moving much underneath the top coats. Probably wouldn't hurt to do a couple test doors though.

It's fine, just do not use the hardener

I'm not sure why you would use Advance or Emerald. Just stick to Renner. as a business advance is not a smart choice because you have to wait about 24 hours to be able to sand it. It would be fine to use it on top of renner but if you are catalyzing it, you need to sand before applying the topcoat. you have to sand regardless =)
