PUT MORE LIPSTICK ON THE PIG - To make cosmetic changes on a software program to make it more appealing to consumers. From "Slang: the authoritative topic-by-topic dictionary of American lingoes from all walks of life" by Paul Dickson (Pocket Books, 1990, 1998).
I found this one while looking for another phrase. I think it's a keeper.
