Paint the Walls, over and over

After the glue is dried and the walls are all sanded down we painted the walls with a good quality exterior latex paint. We USED NO primer just the good quality exterior latex paint. Since we will be putting a total of about 5 coats we used the "Oops" Paint from Lowes ($9.00 a gallon) for the first 3 coats. (that is why the color is so strange). We will get the real color for the final 2 coats.
