Did I ruin paneling by sanding before painting.

Went to pull old 70's wood paneling to upgrade spare bedroom, but saw there's no drywall behind it. Decided to paint the paneling. Lightly sanded off the glossy coat with orbital sander and wiped away dust three times with wet sponge, then let dry for a day. Put on three coats of Kilz2 latex primer (four coats on one wall) and still getting yellowish brown streaking on the walls. Is the old stain seeping out of the wood. Is there anyway to hide it with paint? How do I fix this without ripping it down and drywalling.

You used the wrong primer! Latex primers do a poor job of sealing stains/tannins and don't adhere to some finishes as well as their solvent based counterpart. Kilz2 is also reported to have adhesion issues

Ideally you would have applied one coat of an oil base or pigmented shellac primer followed by 2 coats of latex paint. I'd sand the Kilz2 lightly, apply a coat of oil base primer and then paint.

Just emphasizing what Mark said - original Kilz is decent primer but the latex/Kilz 2 is not good stuff.

I'd actually sand the Kilz 2 pretty aggressively (whereas Mark said lightly) and then apply and oil based primer (I personally use Zinsser primers).
