What are the best adhesive-sealants?

I have just bought a tube of Arc MS-11.Have yet to try it.

Which are the best comparable products?

What makes the difference?

Ive had a lot of success with CT1 when other adhesives have failed.

However, different adhesives have different properties that mean they are better at different jobs.

Most of the "best" no more nails type adhesives are MS polymer based. That's Modfied Silyl polyethers, but not all.

As to why? Quite complex material science, meaning different adhesives bond to different substrates in different ways, and have different finished properties when dry

Thanks.Kind of suck 'em and see.

I imagine it is s no brainer that surface preparation is 90% of the battle.

Adhesive can only ever be as strong as the surfaces it's attached too

And it depends on what you're trying to stick to what. Fibreglass is a favourite trap for silicon slingers- it doesn't bond. At all.
