   I don't know but is Killz the same as Bin Primer? I've used bin with pine knots (worked ok with the knots but not as well as Shellac.

   try the shellac...

   Mark

   I suspect the Killz/Bin primer are alchohol based and the alchohol is a solvent for the marker ink (I use alchohol to clean up Sharpie Ink)

   Measure it with a micrometer, mark it with chalk, cut it with an ax.

   Yes but the shellac forms a hard barrier unlike the bin and killz primer... (Waxed or unwaxed? The shellac experts here will know best)Mark

   Yep! The shellac did the trick. Thank you. Why the heck to they sell Kitz if shellac is better. Live and learn. I'll never use Kilz again.

   There is a Bin stain sealer that has a shellac base - mostly used for covering mold and water stains on sheetrock that would bleed thru regular paint.

    

   I got some at HD1 - measure the board twice, 2 - cut it once, 3 - measure the space where it is supposed to go        4 - get a new board and go back to step 1

   Shellac works better than the shellac based Kilz.When I was a young carpenter we always used shellac to prime knots for painted wood. Shellac ,3lb cut right out of the can. About ten years ago I bought a can of Kilz for the same application. The Kilz worked on some knots. I had to go back a year later,reprime with shellac and repaint the barge boards.

   Zinsser makes a great white pigmented shellac primer. We used it as the first coat to prime all our walls, to deal with whatever was there. Crayon, dark colors, new plaster, etc. Worked great. We did top prime with a regular flat primer, because paint will slide around on the shellac.

   I go with Marks suggestion first.

   However I'd sand off what you did already (if possible)..

   If not...

   Try to wet the area with Acetone (if you can stand that stuff!) and blot up what you can.. Whatever you use see if it dissolves the color. If not then you need some other solvent.

   By the way.. Im not sure how good that plywood is and may ruin the glue used..

   I am not sure but I think I had to do something like that on a wall.. Gang symbols..

   As I remember I had to use that silver spray paint you use on metal chain-link fences.. Then painted over..

   GOOD LUCK!

   "(I use alchohol to clean up Sharpie Ink)"

   Sharpie ink is aclohol based.  I usually use denatured alcohol, but any alcohol will work.

   We bought a house that had previously been owned by heavy smokers. Ceilings were delightfully nicotine stained. Three coats of Kilz, and two coats of ceiling paing. The stains still came through. WTF? Then I realized I had been using the water-based version of Kilz. My mistake. Went back with the oil-based version, one coat, one more coat of ceiling paint. Beautiful. Did you use the water-based version on your plywood? Might be worth a look.

   Bullseye is the product you want, made by Bins. Kilz is a waterbased version fo the same thing. If the marker is showing through the first attempts wipe with denatured alcohol first. Its the solvent for "permanent" marker and should have been used before you did anything. The Bullseye should do the job as your primer coat. Good luck and aloha, Mike
