Yellow Spots In Ceiling UPDATE

[melnjoy]

I have to agree with Steve, about the Kilz being great stuff, but having been in the paint business for years, I have to warn you the the kilz products are primer/sealers not paint, and not designed to be left uncovered without a top coat of paint. On real small "spot" areas where it matches the color of your ceiling or whatever, it is okay, but if used on a large area, you will need a top coat of paint. A lot of painters use this product for sealing in stains from smoke damage, cigarette stains & mildew stains. I know some of them have mildew inhibitors, but as far as I am aware there is no actual mildew killers, for that, you need a product with bleach in it. Just thought I'd pass on that little tid-bit of trivia.

The outside cover for the stove vent is starting to yellow a little. Plastic paint will do the trick. It's more noticeable wearing polarized sunglasses that to the naked eye.

John, I did paint my outside stove vent as it was yellow after one year. I took it off and painted it with white plastic Kote spray paint(got it at WalMart). I see a lot of yellowing on many rv's trim and outside plastic vents and etc. I plan to keep mine looking white!
