Can you change the level of thickness that is applied?

Not that I can remember. Nozzle allows different positions only. It was easy enough to apply the right amount though.

Can this fix leakage in my kitchen sink? Will it stop the leakage?

I'm no plumber, however this product is used to seal around the edges of sinks/baths etc so for that purpose it would help, however if your pipes etc are leaking, most likely not.

How much does the 80ml cover, will this be able to ho round a bath twice?

If it's a modern bath there should be no problem to go round twice, though once should be enough. Just don't put too thick a first coat on and flatten it down with your finger. Then do the next coat and press that down too. You can get a plastic applicator, but the shape of the tubes top should be enough.

Can i remove old sealant and use this or do I have to layer it on top of old sealant?

Hi, always remove the old sealant first and apply it on a nice clean surface. Be carful not to use any oil based products, to clean as the new sealant will not set.
