the intent of the "rubbed effect" is to not have to polish or anything like that. Though i must admit i hate that vinyl sealer they reccomend with the pre cat's, just doesnt sand up as well as conventional sanding sealer. Course my experiance with it's been mainly doing 3-4k square feet of homes with it, hella lot of sanding, so ease of sanding is major. lol.
As a rule of thumb when i am doing side work though, my bids are always useing SW materials, if they want beng. more or menards materials its time and material only. Yes even those of us with the contractor's discounts pay more for SW as opposed to say Glidden, in the end your better off paying that bit more for the better coverage/quality of finish with SW products.
