We regret to hear of the negative experience you have had with our product and we would like to help. In reading your review, it sounds like your paint didn’t give you the coverage and sheen you were expecting. Usually, since this is a two coat maximum coating, if you haven’t gotten proper coverage after your second coat, we recommend allowing your coating to cure for at least two weeks before doing a slight scuff sanding, cleaning your surface and recoating. Adding additional coats of the paint will not increase the sheen, as this is a low luster coating. It does not offer the high sheen our Gloss Porch & Patio paint would, for example. Since you’ve already applied four coats of paint, if you’d like to increase your coating’s sheen, we suggest waiting the full four weeks of cure time before sanding down some of the current coating, cleaning and applying another coat of the higher gloss paint.
