   I am pretty sure the primer should be oil. Then put your latex.

   Pemember that sanding is most important...before the primer, and in between coats.

   Bondo will telegraph.

   Wear a respirator.

   Hope this helps.

   Water based anything is gona raise the "grain" of this artificial board. If you can say such a thing. You'll put it permanently into a bumpy state. I agree on an oil based primer. By the way, I saw some exquisite countertops done by mixing oil based paint into a sealant, like urethane or varnish. It gave a non-opaque translucent beautiful, aquious, and dreamy like finish. Very modern !

   A nugget of advice given to me on this same forum last year:

   If the MDF has been milled (raised panel edge, etc), use a paste wood filler (NOT wood putty) on the milled edge. Sand, then use wood filler on the milled edge, then a light scuff sand again. Gives a very nice, smooth surface. I used MDF panels for several rooms of raised panel wainscoting, paint grade. Looks fabulous.

   I agree with the above respondants, oil-based primer, then your choice of top coat.

   *I've used Benjamin Moore QD30 as a primer on MDF with milled edges with great sucess, followed it up with a coat of Moore's Satin Impervo and the end result looked sprayed on. QD30 is a stain sealer type, oil based primer which I used the first time on MDF because it was all that was handy, glad I did.

   *I have had success in finishing cabinet doors by using automotive primer. this may be a little expensive. I sand first, then prime, sand again. Then I'm ready to spray on a finish coat. The other ways mentioned above are excellent also.You can't miss.L. Siders

   *The aqueous finish I saw in that grooviest of all towns, Seattle. It wasn't that hard to get. They added oil based paint to oil based sealant. They added enough to add color but not to produce opacity. The actual amounts shouldn't be that hard, just stir and paint on a scrap board till you get it right. Keep an eye out for how much you're adding and you can mix yourself more as you go. Greens, yellows and light blues are the colors I've seen and the finished product is really really cool !

   I need to paint some MDF panels. I would like to use latex. Is this the best choice for this material?
