Prime coat 2 is the same thing as Bullseye waterbase or maybe 1-2-3
Zinsser is making that a private label to sell in the big box stores. One store might have it as
Prime coat 2, the other box across the street will call it
fast prime or even
quick prime...... can't keep up with the names. They are doing it that way so the store has its own unique product and won't have to price match the same item since another store won't have the same item.
They don't list it on the Zinsser web site as it is only being offered to one chain of stores. Menard's was the first to do this and then Lowe's and Home Depot followed with their own unique brand name made by Zinsser.
