Mixing isopropyl alky with denatured

[86BGN]

I am testing a new DIY kit and poured isopropyl to test with, I had planned on running denatured but the hardware store was closed. Does anyone know if it is ok to mix the two?, or will there be some sort of chemical reaction and my car blows up in a burst of white flames

Thanks
