4 Quarts of hardener Around 100.00..... 4 quarts of clear around 100.00 =2 gallons 200.00 so therefore one gallon costs (around) 100.00 but if its a cheap price your looking for try enamels or single stage paints....the main point is SPI is SOOOO much better its ALL I use regardless of the price its GREAT clear....as good as 400.00 a gal. clear...Cheap clears are harder to spray well for a newer painter.....or a BDBM....
