SPI Matte Black to match SEM trim black

Hi guys, I have SPI matte black and I'd like to have it match some of the SEM trim black. What mixing ratio do you suggest? Thank you!
 
I haven't tried to match it, but I think trim black is glossier than 4:1 matte black, isn't it? You'd have to over activate it, imo.

I'm not certain, I have used some SEM trim black on some trim moldings and ran out. I would like to use SPI matte black if it's close for the remainder of the job.
 
Knowing how hard it is to match color and gloss levels, I would recommend either redoing everything with SPI Matte Black, or just getting more trim black. Because it's not just the gloss level, I think you will find the trim black to be more brownish looking as well. Making a test panel of the SPI at its stock 4:1 ratio might help you decide. Also those are handy for future reference.
