Not sure this is the right place for this but I wanted to share my experience here since this comes up occasionally and someone might be able to learn from my mistake.
With the obvious dangers of Spraymax 2k, I decided to only use 2k on my topcoat and use the Spraymax 1k (somewhat less toxic and terrifying to use) as the basis for my sealing coats between Createx air-brush touch ups.
DON'T DO THIS! IT will not work!
What I discovered the hard way is that when you have the Spraymax 1k as a base, then apply Createx (and I have no reason to doubt any other brand) touch ups and THEN seal it with a top coat of the SM 1k it will cause your beautiful acyrilic touch ups to wrinkle like a California Raisin that spent too much time in the pool.
The photos here show you what the result looks like.
I did some more testing to discover this the hard way which you can read more detail on in my Sinbad Restoration post:
