Is my epoxy still good?

I have several cans that are partially used. Today I opened one (a can of white) to use, this can only had about two inches in the bottom, and there was a clear liquid over a very thick white colored liquid. I thought it just needed to be stirred, so I stirred, and stirred, and stirred. Still seemed thick and had some small lumps that wouldn't go away.

I just plan to use this batch to pour into some doors to coat where the skin wraps around, so I continued on. I poured it through a strainer into a mixing cup. It barely went through, eventually stopped with about an inch in the bottom of the funnel. I added the appropriate amount of the part B. It looks almost normal after stirring that in.

My question is, could I spray this if I wanted to? Would it still work fine, have good durability, etc? I have another open gallon of white that is almost full (not sure why I just didn't finish the first can of white) and a can of black that's almost empty that I wanted to use to make grey.

How do I decide if that is OK? And how thick can the black be if I'm just using it for tinting?
 
Thought I'd add some pictures, first one shows how much was in the can, second one some of the lumps that wouldn't go away.




 
I would mix until lumps go away. If using all of it you can mix in the can and close the lid and shake the hell out of it the extra space in the can will allow the lumps to be nicely slammed around while shaking. Let induce as usual and strain any dried clumps that might have come off the sides while shaking. That's what I do and I think you'll be fine. You could put it into a clean can and do the same procedure also I do that when mixing from a new container when I only need a little.
 
In the future try to keep the rim of your can cleaner so it seals correctly. Epoxy lasts a very long time if sealed properly. I simply apply a piece of 1 1/2" masking tape around the lip of the can and use it as a pour spout. Then wipe the rim clean with a paper towel.

X2 on keeping the rim clean. I keep a supply of throw away acid brushes and they work well to brush the paint out of the can rims.

I usually keep another gallon can to pour half of new epoxy into that way I don't spill as much when I pour it into the cup. That way one can stays sealed longer. I hate it when I spill it.
 
I was hoping Barry would chime in. Clearly something has evaporated, I was hoping to know for sure if I can Just reduce it a little extra so it will spray ok, or will
That affect durability?
