River Rock Paint by Ralph Lauren is definitely beautiful however, after applying 3 coats following can instructions to a "T", I just can't seem to get rid of the veritcal lines. To be honest, I can't live with those darn lines. The color and texture are beautiful enough -AND- I am stubborn enough to go for a 4th coat since the lines did seem to decrease in intensity with each coat, I am just waiting for the energy. God help the person who decides to paint over the dark color I chose! I read on another website that you must move quickly and be sure not to skimp on coverage. Well, I am going to slather it on fast and furiously this time and if it doesn't work I too will be going to Sherwin Williams. I painted the exterior of my home with their 20 yr warrenty "Super Paint" which costs about $5 less per gallon than Ralph Lauren interior River Rock and I was MORE than satisfied with the outcome. I'll let you know how the 4th coat turns out.
