Sandable Primer for Smooth Professional wood door faceing
I am trimming out my doors and windows with pine wood. I sanded with 100, 150 and 220 grit. The resin in the pine is harder than the other pith wood and does not smooth out because it removes the softer pith wood quicker.
I painted with SW Pro Classic with 3 coats it still showes the wood grain.
1. Is there a good sandable wood primer which will give a good build up so I can sand it smooth and not show the woodgrain before I put on the final paint?
2. How many coats of paint should I put on after the primer?
3. I see where some use a final coat of water base Poly, Does that help to smooth out the final finish and some people put it in the latex paint. Is that a better formlula than just the latex?
4. Spray, china brush,foam brush. Which is better?
5. What grits of sandpaper at each stage?
What are your recommendations?

You need a a good oil-based primer to seal the tannins in wood (such as pine). Oil-based primers also tend to be more sandable than water-based. Zinsser Coverstain is a good choice. Be aware, though, that oil-based paints/primers are more difficult to apply than their water-based counterparts.
Why are you looking for good build-up? The primer is not being used to fill in low spots... is it?
I rarely sand beyond 120 (or 100 grit if it's well-worn sandpaper) grit for painted millwork. it's not worth it as you wont see sanding marks from 120 grit.
I also usually use pre-primed wood for paint grade. It saves a lot of work and is often cheaper.
In my opinion, foam brushes do not work well for paint. I use them as throw-aways for stain or BIN.
1 coat or primer and 2 topcoats should be all that is needed.
Benjamin Moore Underbody Alkyd Primer. High solids. Sandable (after 24hrs) Powders off nicely.
