Question: Is blue devil hg repair safe?

Hi, have an old 89 maxima SE. I believe its having some headgasket issues I.e. rough idle, white smoke, getting warm...
It has 220k so I'm not sure if I want to dive into a head gasket with limited resources and tools... My question is will the blue devil hg seal harm my engine further, or is it worth a shot in the dark to see if it will seal the leak and buy me 5 or 6k until I buy a different motor for it
