Fixing dents and replacing latch on wooden chest?

A linen closet with cat urine soaked hardwood floor and sheetrock was left for years. I cleaned it best I could and decided to paint over it to try and seal in the odor. Today, I put 2 coats of zinzer bullseye 123 water based primer, with the intention of then painting it. However, I have since read that zinzer bin is the best thing around for sealing in cat odor. Can I apply this over the zinzer bullseye water based primer? If so, how soon? Also, is it necessary to paint over the zinzer bin, or can I leave it without a topcoat, as cosmetics are not important here as it's not a visible area. Note that the area is subject to wear and tear as we use it for storage of heavy boxes, and I don't want the sealant to be worn down. If paint is necessary, what kind?

Interior doors were originally painted with oil base paint (so I was told), then were repainted years later with latex paint (so I was told). Within a week, a bump & a scuff here & there.... now the latex paint is peeling off in sheets. You can literally just peel it right off in sheets. However, it's not all coming off so easily. It will be very time consuming to remove it all off by just peeling it off the entire doors. We are talking about maybe 10 doors. Option 1: Buy new primed doors, paint & set new hinges etc, etc. Option 2: Sand blast the latex top coat off Option 3: Use a pressure washer to remove latex top coat Option 4: repaint doors with latex paint still on (some paint peeled off, some not) with oil base primer, then oil base paint. I think sand blasting will ruin the entire the door, wood, finish & all. I think power washing will ruin these interior hollow core interior doors. I think they will water log, swell, eventually rot & come apart. I think buying new doors & having to cut out for the hinges etc is going to be time consuming, not cost effective & a PITA.... more trouble than its worth when considering other options. Option 4 is what three (3) painters have recommend under the circumstances. I don't buy it, but I ain't no painter either. I say, if the latex paint ain't stuck to the existing paint from years ago, its going to continue to peel off, therefore the oil base primer & paint top coats will also peel off with it. Painters insist that putting on a coat of oil base primer, then a coat of oil base paint, should seal the paint/door & the paint shouldn't peel off. In the end, what are your thoughts & suggestions? Buy new doors, sand blast, power wash, or repaint over latex with oil base primer & paint..... or other opinions. I'm up for any reasonable, serious options at this point. Thanks......
