blue spot bleeding through walls after primer
Some help needed here.
I TSP'd the walls to get them ready for primer. As I sprayed the TSP on the wall I noticed a blue spot a little smaller than a dime start to bleed like ink. I wiped it down and then primered over it. Very quickly the blue spot bleed through as if never even primered over. I spackled and primered over the spot atleast 7 times and it still bleeds through as if fresh.
I've been using Killz2 primer as I heard this was the best.
My first question is what can this blue spot be?
And how do I get rid of it?
Thanks for any help.

In fact, I find it...not good at all
The original (oil-based) Kilz is pretty good though
Regardless, you need to seal that well
At this point I'd take the next step up
I'd recommend a shellac-based primer/sealer
The BIN is my personal favorite, and it comes in a spray can so there's no need to buy a throw-away brush
