Latex over oil???

[GPW]

I painted my TD in ooil based paint , and it needs repainting ...on the roof anyway...the oil was a PIA... slow drying and picked up every bug and bit of fluff in the neighborhood... After doing some exterior house trim painting with the latex enamel , it was so EASY to use and dried quick ... Hmmmm???
Now the question is , if I sanded the oil really well , and primed it with ??? could I use the latex???

You'll have to sand your current finish being careful to get every nook and cranny. Wipe it down with mineral spirits and allow to dry. Apply a coat of Zinzer Bullseye primer and allow that to dry for at least 12 hours. Then you should be able to top coat with no problems. The Zinzer primer will take about 7 days to fully bond with the base paint.

I've had to deal with this problem alot here at work.
I would not EVER put any type of latex over an oil base, it will come back and bite you in the A$$ later on.

I worked in the paint industry for several years. There is no problem painting latex over oil paint. If the oil was a gloss, you will need to lightly sand to give something for the paint to stick too. One thing to keep in mind, when a latex paint is dry to touch it is not dry. It takes several weeks for the paint to fully cure.

I know there have been other discussions on this, but since we have new people joining, would like to get feedback confirmation on what I remember....

First, latex paints have gotten better, while oil based have gotten worse because of gov't regs about environmental stuff....

So, we can use oil, latex, interlux (marine)... I'm curious about which latex would resist staining better.... would a semi-gloss be good enough, or would it have to be a gloss paint (which would reflect all my bad body work)... Oil would be my abosolute last choice....

But, am still up in the air between latex semi-gloss and interlux brightside... I plan on using white to match my van, so the staining would occur pretty quick, based on past experience.

And washability is a big concern.. don't want to repaint every year.. I'm making sure I do not have a flat roof so water should run off fairly fast.

I agree with Sierrajack above. If it is glossy, sand it lightly, then use a good primer. The Zinsser is good stuff and bonds to about anything. You shouldn't have any problems. Primer is the key.

Thanks guys, Now would that be the shellac based Zinsser or the WB ???Sorry to be so DUMB!!!

Since you are going to put a latex topcoat on, you will want to use the water-based Zinsser primer.

Thanks !!! my problem was caused by not having a shelter for my new TD and it sat in the Sun/rain for a year in my yard... Now , I've built a shed to house the TD and will be able to keep a good durable finish on it with little trouble ...The latex gloss house paint was so easy to use, I really wanted to go with this on the roof/hatch areas ...the sides are fine ...
Since I'm a professional artist (Yeah, but I gotta' paint my own house), application of paint is EASY , but that slow drying oil enamel was a sticky bumpy mess...Argh !!!
Thanks again for all the help!!!!! ...I'll try to post some pics when it's done ...
