Slant six paint recommendation, for whatever its worth.
I was planning on trying the bill Hirsch paint next time I have the chance. I am a big believer in most POR 15 products as they work well for me. My exp is that they are very durable and do as advertised.
But I will never waste the money on their engine paint again. I did so once. It didn't cover worth crap. I ended up recoating with a duplicolor spray can. Which as of the last few years ghas missed badly on the "Mopar blue".
