[Histonet] Can DAB block an epitope??

I was hoping to run a chromogenic immuno to check if two proteins colocalize.
Since both antibodies are made in rabbit, I was going to stain one and visualize with DAB and then heat retrieve (pressure or steam) to drop off the first antibody and restain with my second rabbit antibody using a different color to visualize.
How likely, if at all will the DAB precipitate block / mask the epitope of my second antibody if indeed they are in a similar location?
Any info would be greatly appreciated.
