"Not good. Dont know if I did something wrong, or I just got a duff tin. It leaked everywhere when spraying. Got more on the floor and on my hands than on the job. I have used the "Old 500ml Pro Kote Primer from Screwfix " loads of times with no issues. I actually used the rest of an old tin before trying this new stuff (comes in different tin and only 400ml) and would be wary about buying it again."
