2K rattle cans

Any advice on using 2K clear spray in cans , will it go on non 2K paint, or is it 2K specific?
Thanks in advance.

As far as I know, you can’t put 2k clear over acrylic base. The acrylic shrinks over time and the clear cracks. 2k over 1k is ok I believe but the base has to be completely cured first.
