Hey guys, having trouble with primer and looking for thoughts. Using Azkonobel 463-12-8 that I bought 3 months ago and kept in a temperature controlled environment. Sprayed for the first time yesterday with the purple gun from harbor freight. After playing with the settings I feel like a got a good spray but the consistency and color of the primer was off. It was very watery and sprayed mostly clear. Yellow with a hint of green when I really layered it on while testing. When I’ve seen it sprayed in videos it looks very green and easy to tell where you’ve sprayed and I’m not getting that. See pics. I cleaned the gun and used 1:1 mix with a quick stir. Maybe 20 seconds. Let it sit for 30 min and restirred for 2 min. Then filtered it into the gun. The parts were prepped using a scotchbright pad to scuff and then acetone to clean. Not sure what I did wrong. Any thoughts?

I see that you are using the paint stirrer contraption. I found out the hard way that the stirrer didn't work very well for the epoxy primer that had been sat for a while. The plastic fan blade in the stirrer doesn't do a very good job at mixing the very high solid content of the epoxy primer that I was using. I ended up using the Home Depot paint stirrer wooden stick. If you remove the stirrer, check and see if there are solid at the bottom of your paint can, and see if there are solids getting stuck on the plastic fan blade. If you find any of them, then you want to stir the paint by hand.
I use the same lids as the OP and have never had a problem mixing my Akzo. But, if the cans have sat for a while without being mixed, I spend quite a bit of time spinning the handles to mix the primer before using it. After pouring the primer into the paint cup I stir it with a tongue depressor. I then put the lid and cap on and shake the cup every few minutes while waiting for the 30 minute setup period to expire prior to spraying.

I think although you applied the required :30 min induction time I feel you may not have stirred often enough to allow an effective molecular cross-linking of the catalyst to primer. I would do a test sample with a more focused induction stirring. Not aggressive, but more often. Think of making old style pudding where it would stick and burn at the bottom of the pan.
Well, you just answered my question that has been lingering: "are those stirring lids good for Akzo primer" In my 10 years of building, I always wanted to try them but always reverted back to the paint stick and mixing paddle on my drill. Thanks- we learn something from every failed experiment.
I've used these stirring lids to prime all the parts in my empennage, fuselage and wings with Akzo and they have worked great for me. These lids, along with the 3M PPS 2.0 system, make mixing, pouring and cleanup a breeze.

I used the stiring lids for AKZO as well and was happy with them.
They work well if used regularly.
But they don’t seal airtight so if you leave them long enough the VOCs will gas off and you’ll be left with sludge or even crystals for the part B.
If you plan on not painting for a few months then you might want to stick the regular lids back on.
