Been a Three Bond 1187 guy for years and when it gets squished in it's more rounded and flattened as it is relaxes before it dries.
Have used the blue for split tanks, new Mac 10-10 fuel lines that aren't properly sized for the job, just smear on some blue goo and pull through. No more leaky. And is easy to clean up when the next line goes in. So I guess I can see where it would work on a cylinder base too. I tend to think that they(2 stroke sealants) all have a place and it's up to us to find it.
