I recently completed a storage unit made from birch plywood. Based on things I have read in this newsgroup in the past, I used an alxyd primer followed by two coats of semi-gloss alkyd paint. I found the alkyd paint to be thick enough where I saw brush marks in a few places after it dried. Probably nobody but me will notice but you know how it is - you want your project to be as perfect as you can. I choose alkyd because it really dries hard so I shouldn't see marks from things sitting on top of the storage unit. If you have done something similar would you have thinned it a little or would you have used the semi gloss latex?
TIA.
