Gloss finish tutorials for MDF?

[thewisteron]

Ok, I finally have time to get back to my project. I used MDF for my cab. I bondo'd the big imperfections and bought some rustoleum primer filler to spray the rest. I've given it a couple of spray coats and sanding,  but I can still see some tiny cavities. I don't want to do a gloss finish with tiny imperfections.  Are there any tutorials out there for giving a gloss finish for MDF?

     Poly glaze putty (from auto supply) mixes just like bondo but sands easier and is designed for pin holes... fill your small imperfections with this (level not a big goob) lightly sand whole thing and reprime, A gloss finish will require ultra flat and not sanded with anything coarser than 400grit -1000 or you will see the scratches through the gloss, Black is the worst color, due to its absence of color and will require a perfect surface.

So something like this?

Pricier than Bondo,  but maybe I'll give it a shot.  And of course I was planning on black. Maybe I'll have to rethink that.
