I used Tubliss for years aand never found a tyre that was 100 % tight. All of them lost air, some quickly, some slowly. Even on brand new rims. Then I started to use slime and one day when I changed my MTB tyres to tubeless I found this:

Buy Finish Line Tubeless Tyre Sealant | ROSE Bikes

It made all my tyres air tight and it is water-soluble so its easy to clean up the mess when changing tyres. 180ml for a rear tyre.
In the meantime I use Michelin mousses and have no issues...

Cheers for the info!

Are you stating that you need 180ml each time you change the rear tyre?

Yes unfortunately. Please do not try it, I just had a mate on the phone and he said he had massive problems with it when he dropped the pressure below 8 psi. He then tried the slime (https://www.slime.com/de/products/bike/sealants/tube-sealant.php) and said it worked way better.
I had no problems with either one, but I don't want to risk that you get problems with something I recommended.
Therefore i withdraw my recommendation, sorry SCB!

I do exactly same ....then put 30psi in and leave to seal ....I use XT754 at 6psi and it'll hold at 6 no problem .....I think the key is ...shitloads of soapy water and high pressure for a few days to seal .....I used to fit tyre and set it at the riding pressure... they always leaked

Strange, I never ever manged to get the 754 tight. Guess I must give it another try once I am fit again and the fucking snow is gone...
