I have a 11 year old house. It has “some kinda” synthetic siding (which is in great shape and still holding it’s original paint).
My problem is with the long trim pieces (pine maybe?). The paint started peeling on the trim about 3 years ago. So 2 years ago I scraped and sanded then primed and painted. The paint is coming off again. Easily peels off in spots with my fingernail. Peels down to the bare wood.
I don’t remember what I primed with. But I painted with a latex. It appears to me the paint is stickng pretty good with the primer, but the primer didn’t stick to the wood.
Is there a “bullet proof” primer? Like maybe Kilz (oil based) or Zinzer?
Any recommendations would be greatly appreciated. I hope to find something that will last longer than a couple years! Thanks!

Peach full,
easy feelin'.
Peeling to bare wood is usually a sign of a moisture problem, although your primer (if latex) may have been part of the problem. Exterior trim should almost always be backprimed (primed on all sides including cuts) with an alkyd primer. The one I like is Cabot's Problem Solver Alkyd with 10% Penetrol and mildewcide added.
That being said, new-growth pine (if that's what you trim is) can be expected to last only 5-8 years, even if painted well - it just doesn't hold up, especially if not backprimed. Better choices include cedar, spanish cedar, Azek and Koma - the last two being synthetics which have their own set of issues (like expansion) but which will not rot or peel paint.

Nothing is bullet proof. To many variables
As far as your problem, hard to know with out seeing it. As Jeff mentioned most likely moisture from somewhere. Or an improperly prepared surface when you primed.(ie: wasn't completely scraped or there were blisters) Was anything on the back of the primer that peeled away.
Could of been cheap primer, oil primer on a damp surface. Backpriming is a necessity anymore with wood, since your wood is already on you can remove it and use one of the woods or engineered products that Jeff suggested
or
if you don't want to replace the wood try to find the moisture problem, if that is it, make sure the wood is properly and completely scraped and the edges of the scraped areas sanded smooth. You will find more loose areas this way. Even better but not always practicable completely remove all existing paint on area you want to refinish.
I prefer an oil primer with 2 topcoats of 100% acrylic paint. On stubborn areas I have had some success with Zinnzer's PeelStop, it's a binding primer
Thanks Barry. Obviously my house trim won't be coming off the house and getting replaced or backprimed! So I'll take your advice to remove all the paint and use 2 good topcoats.
Thanks!
