Aerokroil vs Silkroil? Which is better?

I have the silo croil and if you spray it several times in a two day period it will creep into the thread bolts and will loosen the bolts.I’ve never used a better product it’s really great you have to be patient and it will work.

I consider it to be far superior to WD-40 both as a penetrating and a lubricating oil.

Before using, should I heat the seized hex bolt, or the surrounding cast iron?

I'd let the kroil sit for a while and try it before heating. A torch is usually the 2nd to last option before drilling
