in the history of the universe. Now I'm making mistakes never before seen or entered into the heart of man.
I put 40% too much activator in a batch of high build primer. By the time I got to the 4th panel the first three were dry. I can't find any solution on the internets on how to fix this.
Obed®, shed some wisdom so I won't have to show up at Finishmasters and embarrass myself before strangers. Please!

Man you’ve argued every piece of advice I’ve given so far, why stop now?
In all seriousness, You worried about the integrity of the primer coat because it cured too fast?

Now simma on down and advise me.
Just because I argue doesn't mean I don't take your advice into consideration. I pay close attention to you.
I'm worried about the integrity of the primer because I added 40% too much activator. Cleaning the gun was quite a chore.

My second one was a serious question

It’s an epoxy primer right? If it dried it is what it is. What’s your overall concern about the speed at which it cured/dried? If anything, I would suspect the coat might be a little harder, not softer or weaker. In other words, if you screwed up, feels like you screwed up in the right direction.
The downside would be it getting too viscous to spray properly too fast.

My first response was another joke.

I apologize for the wavering but I'm trying to laugh this off and it's a struggle.
I took the second question as serious. Ignorance is no joking matter.

Did you get everything sprayed that you wanted to spray?

If so, put it in the laugh file. All you really did was squander a little working time with thst batch of primer. If you hit what you intended to hit, score one for the good guys.

You might have affected the self leveling properties of the primer just a little bit, giving a bit more of the orange peel peaks and valleys. If the problem existed, it would present more on the later panels you did. If you notice it, nothing a bit more sanding that you love so much won’t cure.

I understand the purpose of sanding high build is to level it first which requires little pressure and after it's level to sand again with a finer grade paper until the last sanding is 400, 500 or perhaps even 600 grit paper.
The first sanding is to level and the remainder are to remove previous scratches so the sealer can fill them. That ask nothing but color and covering from the basecoat(s).
I was going to sand these first 4 by hand but I'm giving thought to using a random orbital with a soft pad and some, perhaps 220 grit disc just to knock down most of the orange peel.
What'd ya think?

That changed my attitude toward this project.

It's a fantastic read. I planned to let the high build sit for a week but no one ever mentioned the fact that the depth of the scratches or the length of the time the high build was left to gas off would be more than that. I know most of the cheaper paints are made with the repair shops in mind but I had no idea that sanding high build in a day or two would defeat the purpose.
I was rushing through everything with two misconceptions. First that after the 10-15 mins flash time I would quickly approach the time when the next coat wouldn't chemically bond and that when paint manufacturers specify 180 grit paper they are really saying that 180 creates the deepest scratches that particular product will fill. I viewed the minimum as the maximum on both concepts.
I have reviewed your advice on body putty in those dings and decided to sand them our now and do the putty fill before I proceed. With the high build being the last coat on top of them and a couple of good Hutchins sanding board to find them easily. If there's any consolation it's that these are only a small portion of the entire project and rather than having to back up a mile I'm only backing up half a block.
