What a nice man you are to share your expertise, Paulie. Thankies so much...I wish I had heard you better before I bought the damned stuff.
Can I store the oil primer for any considerable length of time? Some of my exterior trim needs repainting...could I use it there and get a latex primer for the bedroom instead?
Thankies again. Generous people bowl me over, Paulie.
That stuff can sit for a while. But you'll have to take a stick and stir up the crap from the bottom of the can and then lid it and give it a really good shake, because the oil tends to separate from the rest of the mixture and sit on top of the crud when it sits for a long time.
Here's the only thing I ever use oil based primers for:
-any metal surfaces
-anywhere wallpaper has been removed, to seal in the leftover glue residue
-water stains
-completely brand new raw wood
-rust spots
If you have trim outside that needs to be painted, you have to scrape all the loose peeling paint off, give it a good sand, and then prime it with this:
It's a latex based exterior primer that's great for bare wood spots. It's actually fine for brand new raw wood too. I only use oil primers on brand new wood if it's interior molding. Otherwise, this product works great. It resists tannin bleed. I'd recommend hitting any spots twice that you use it on. Then just use a regular latex based finish.
I don't know why people think oil primers are so necessary for so many things. They're not worth the trouble in most cases. They're really only necessary for what I mentioned above, and a few other random things that you'd probably never be doing yourself anyway.
