New ProSeal onto old ProSeal?

Hi All,

I had to open my fuel tank for repair. Do I need to scotch-bright all of the old proseal until I get shiny metal, or will wet/new proseal adhere to the old stuff and make a decent seal? ( I did use a flat metal scraping tool and have removed the bulk of the old stuff.)

Thanks in advance,

I can only tell you what I did - I scuffed it and the surrounding metal and made sure that the new proseal carried out to the fresh metal. I gave it a wipe with acetone before applying.
